McGrath Locks F54 ANSI Mortice Lock - Grade 1 Stainless Steel, Latch and Deadbolt - 70mm Backset, 92mm Pitch

The McGrath Locks F54 is a Grade 1 commercial mortice lock body in the ANSI format - a 70mm backset, 92mm pitch and a 203 x 32mm faceplate, in SS304 stainless steel, cycle tested to 1,000,000 operations. It carries both a 19mm anti-friction latch and a 25.4mm (1 inch) throw deadbolt, and it is the mortice McGrath specifies for the Bardon commercial smart lock. It is a mechanical body only: no electronics, no batteries, no app. The smart lock furniture sits over it and does the thinking.

Its sister, the F05, is the same body without the deadbolt. That single difference decides which one you want: the F54 where a mechanical deadbolt is specifically required and the door is not a fire door, the F05 for smart-lock and fire-door installs where a deadbolt is either unnecessary or not permitted - the key difference and which one to choose are laid out in our ANSI blog, and the short version is on this page.

The cylinder is not included. The F54 takes a threaded Kawneer mortice cylinder, not the Euro profile cylinder used across the rest of the McGrath range - the Kawneer cylinder catch is the most common ordering mistake on ANSI bodies. If you are replacing a body you cannot identify, start with the identification steps in our McGrath mortice guide.

Grade 1 - Heavy-Duty Commercial
Grade 1 and cycle tested to 1,000,000 operations, the F54 is built for high-traffic commercial doors - twice the cycle rating of the McGrath Euro 85 bodies. For how lockset grading and cycle ratings relate to the Australian standards, see Chapter 11 - durability grades and corrosion grades.

Compatible McGrath Smart Locks

The ANSI bodies are McGrath's commercial-format mortices. Only one McGrath smart lock is specified on them, and it is the one the fire assessments were run with.

Host lock What it is How this mortice fits in
McGrath Bardon Commercial smart lever lock - raised Braille buttons, DDA-compliant lever, fire assessed The Bardon's data sheet names the F05 and F54 as its ANSI mortice options and the lock ships without one. Choose the F54 where a mechanical deadbolt is wanted on a non-fire door; on a fire door the assessed configuration has no operable deadbolt - see Fire Door Use.

Not for the A210, A231, A236 or NX5 (85mm-pitch Euro bodies), the NX1 and Albion (60/50 spindle mortice) or the NX6 / NX6W (Euro 60/68 three-point body). The Windsor, Hamilton and Stafford fire assessments use tubular latches and dormakaba MS2602 / MS2902 mortices, not an ANSI body. The five McGrath mortice families are compared in our range guide.

Key Features

  • Grade 1 mortice lock for commercial and high-use doors - cycle tested to 1,000,000 operations. Where lockset grades sit against AS 4145.2 is covered in Chapter 11.
  • 19mm anti-friction latch plus a 25.4mm (1 inch) throw deadbolt in one case - what a genuine deadbolt adds over a latch is explained in Chapter 01 - mortice deadbolt and our note on deadbolt projection.
  • 70mm backset (B) and 92mm pitch (D) - the ANSI standard preparation, not the 85mm pitch of the McGrath Euro bodies. Confirm yours with how to measure your lock backset before ordering.
  • Reversible latch and field-changeable handing - one body suits left- and right-hand doors, and it can be re-handed on site.
  • 8mm square spindle hub driving the smart lock furniture; SS304 stainless steel case, latch and deadbolt in a satin stainless finish.
  • Accepts a threaded Kawneer mortice cylinder (sold separately) - the mechanical key override for the host smart lock lives here. Note the Kawneer cylinder catch: a Euro cylinder will not fit.
  • Fire assessed as the Bardon's tested mortice on Firecore and E-Core doorsets - with the deadbolt made inoperable. Full conditions under Fire Door Use.
  • 203 x 32 x 4.5mm faceplate and a 147mm-high case - the same footprint on the F05 and the F54, so swapping between them is a straight replacement in the existing mortice slot.

Fire Door Use - Assessed with the McGrath Bardon

The F54 is the mortice that was physically tested. Jensen Hughes Fire Testing fitted a McGrath Bardon to an F54 ANSI mortice with the 350 x 85mm Bardon scar plate and ran two pilot-scale fire tests to AS 1530.4:2014 - one on a Firecore doorset and one on an E-Core doorset, each for 120 minutes - then assessed the result under AS 1905.1:2015. The headline assessed figure is FRL -/120/30, and the reports are linked in Download PDF Resources.

  • The deadbolt must be made inoperable. Every one of the four assessment reports carries the same condition: a deadbolt left protruding can stop the door closing, AS 1905.1 does not permit that, and the FRL is valid only with the deadbolt function disabled. On a fire door the F54 is fitted as a latch-only body - which is exactly what the F05 is by design. The fire-door compliance section of our ANSI blog explains why this is where most mistakes happen.
  • The FRL is one-way. The batteries sat on the exposed side in the tested system, so the assessment covers fire attack from the battery (interior) side only. Ask us before specifying for a door that must resist fire from both sides.
  • Retrofits need the scar plate. Without the Bardon scar plate the assessment applies only to a door with no pre-existing holes - the plate is part of the tested assembly over a redundant cut-out, not a cosmetic cover. See scar and adaptor plates.
  • The system FRL is the lower of the hardware and the doorset. A -/120/30 lockset on a -/60/30 door is a -/60/30 opening. Find your door's rating on its compliance tag and read what the FRL numbers mean.

One thing worth knowing before you order for a fire door: the two test reports are titled for the F54, but the master range assessments write their Bardon rows against the F05 without the deadbolt. Our reading is that the tested body was an F54 with its deadbolt disconnected, so the assessed configuration is a latch-only ANSI mortice - the F05 as sold, or the F54 with the deadbolt disabled. We are confirming the exact wording with LSC; until then, specify the F05 on a fire door unless you have a reason to need the F54. Chapter 05 covers Firecore, E-Core and Pyropanel cores and where fire doors are required in Queensland; Chapter 11 covers AS 1905.1. The Bardon page carries the full fire assessment section.

Fire doors are a system, not a lock
A certified doorset, the hinges, the closer and the lock are assessed together, and a fire door in a Queensland apartment or commercial building is usually also a body corporate matter. Our guides cover the compliance summary, what a fire certificate looks like, why you cannot just swap the lock and why we do not recommend DIY on apartment fire doors. Pre-1990 doors: read about asbestos before anyone drills. Terry's offers advice and installation across the Gold Coast.

What's in the Box

MLF54ANSIMLSSS
  • 1 x McGrath F54 ANSI mortice lock body (Grade 1, SS304, 70mm backset, latch and deadbolt)
  • 1 x stainless steel faceplate (203 x 32mm)
  • Strike plate
  • Fixing screws

Note: the threaded Kawneer cylinder and the smart lock furniture are not included; the Bardon scar plate is a separate item - see Accessories and Spares.

Suitable Uses

  • Commercial and institutional buildings, offices and high-traffic access doors - the duty class the Grade 1 rating and 1,000,000-cycle test are for.
  • The McGrath Bardon on any door prepared for an ANSI mortice - hotel, strata and aged-care corridors are its home ground. The door type compatibility matrix in Chapter 04 shows where each McGrath lock belongs.
  • Non-fire commercial doors where a mechanical deadbolt is specifically required. On fire doors the deadbolt must be made inoperable - see Fire Door Use - so for a fire door the F05 is usually the cleaner specification.
  • Replacing a worn or damaged ANSI body under an existing lock without disturbing the furniture - measure the backset and faceplate first; the range gallery shows the ANSI pair beside the 60/68 body.
  • Regular front doors and internal doors in commercial fit-outs where a keyed Kawneer cylinder is wanted as the mechanical backup to a smart lock with a backup key.
Not Suitable For
The Euro-profile McGrath locks - the A210, A231, A236, NX5, NX1, Albion, NX6 and NX6W are all drilled for their own mortice families and none is specified on an ANSI body; see the compatibility table above. Sliding or bifold doors - use the 28mm or 35mm Euro 85 hook body with the A231 sliding-door lock, or browse sliding-door smart locks. Euro cylinders - the cylinder pocket is threaded for a Kawneer cylinder; nothing in our cylinders and barrels category for the Euro-profile McGrath locks will fit it. Fire doors with the deadbolt operable - the assessed FRL applies only with the deadbolt function disabled; a deadbolt that can be left protruding is not permitted under AS 1905.1 (Fire Door Use).

Available Finish Options

  • Satin Stainless Steel

Finish selection does not affect functionality, compliance, or performance. Only the 32mm faceplate edge is visible once the body is fitted.

F05 or F54 - Latch Only, or Latch Plus Deadbolt

The two McGrath ANSI bodies share everything - Grade 1 duty, 70mm backset, 92mm pitch, 203 x 32mm faceplate, 147 x 99.5 x 22mm case, 19mm anti-friction latch, Kawneer cylinder, 1,000,000 cycles (what they have in common) - except one thing:

  • F05 is a latch-only mortice lock with no deadbolt.
  • F54 (this product) adds a 25.4mm (1 inch) throw mechanical deadbolt.

Fitting a smart lock, or fitting hardware to a fire-rated door? The F05 is usually the safer and simpler choice. The F54 is for doors where a mechanical deadbolt is specifically required and the compliance implications are understood - on a fire door its deadbolt must be made inoperable, at which point it is doing the F05's job.

The 60/50 bodies have no cylinder aperture and no pitch - the key override on those locks is in the escutcheon, not the mortice (why there is no keyhole). Fastest family test: count the bolts, check for a keyhole, then measure the backset - an ANSI body is the only McGrath mortice with a 32mm-wide faceplate.

Accessories and Spares

The ANSI bodies take a threaded Kawneer mortice cylinder, which is sold separately - we do not list one alongside the Euro-profile McGrath cylinders in our cylinders and barrels category, so ask us to quote the cylinder and keying you need with the body. The cylinder note in our ANSI blog explains why a Euro cylinder will not fit an ANSI body, and vice versa. The items below are the parts that belong with this body on a Bardon install.

Frequently Asked Questions

What is the difference between the F05 and the F54, and which do I need?
The F05 is latch-only; the F54 adds a 25.4mm mechanical deadbolt. Everything else is identical. For a smart-lock install or a fire door the F05 is usually the right body; the F54 is for doors where a mechanical deadbolt is specifically required. Our blog walks through which one to choose and smart lock compatibility in practice.
Is the cylinder supplied?
No. The F54 accepts a threaded Kawneer mortice cylinder, sold separately, and it will not take the Euro profile cylinders used on the other McGrath locks - the cylinder note in our ANSI guide and the Kawneer cylinder catch in the mortice guide both cover this. The cylinder is the mechanical key override for the smart lock on the door.
Can it be used on a fire door?
Yes, with the deadbolt made inoperable and as part of an assessed doorset. The Bardon was fire tested on the F54 with the McGrath scar plate on Firecore and E-Core doorsets and assessed at -/120/30, but every report conditions that figure on the deadbolt function being disabled, on one-way fire attack, and on the scar plate being fitted over any pre-existing holes. The full picture is under Fire Door Use; the compliance context is in the F05 vs F54 blog and which smart locks are compliant on apartment fire doors.
Is it suitable for high-traffic use?
Yes. The F54 is Grade 1 and cycle tested to 1,000,000 operations - the highest-duty mortice in the McGrath range, twice the rating of the Euro 85 bodies. Chapter 11 explains how cycle ratings map to the Australian durability grades.
What backset is this, and how do I check mine?
70mm, with a 92mm pitch - the ANSI standard preparation. Measure from the door edge to the centre of the existing spindle; our backset guide shows exactly where to put the tape, and the standard Australian sizes shows how 70mm sits against the 60mm most residential doors use. A body with the wrong backset will not line the spindle up with the furniture.

Additional Information

  • Pitch is what separates the ANSI bodies from the rest of the range. The McGrath Euro bodies are drilled at 85mm between spindle and cylinder; the ANSI pair is 92mm. A body with the right backset but the wrong pitch will not line up with the furniture. Chapter 02 covers the mortice lever and long-plate mortice measuring routine, bored versus mortice door preparation, and why backset is less forgiving on a smart lock.
  • Disabling the deadbolt on a fire door. On the Bardon the deadbolt is driven from the internal turn snib; the assessments require the deadbolt function to be disabled, and McGrath sells a blank disc to cover the snib aperture once the snib is removed. Confirm the method with us or LSC before the door is signed off - a deadbolt that can still be thrown voids the assessed FRL. Read what an internal snib disables for the smart-lock side of the same question.
  • Minimum door thickness 45mm. This figure comes from the F05 side of the range and is carried across to the F54 on the strength of the shared case - confirm with us for a thin door. Chapter 02 covers door thickness and the host lock's spindle length is the other limit - the Bardon guide documents ANSI spindle lengths for doors up to 100mm thick, although its data sheet quotes 35 to 55mm as the standard range - see its specifications.
  • No Lockton or dormakaba equivalent. The Lockton E-Series Euro smart mortice bodies are 85mm-pitch Euro bodies - the SML-H70 shares the 70mm backset and nothing else. The dormakaba MS2602 that the Windsor, Hamilton and Stafford fire assessments name is a 60mm Euro primary mortice for those lever locks; it is not an ANSI body and is not assessed with the Bardon. Our guide keeps the cross-brand equivalents straight.
  • Strike alignment decides how the deadbolt behaves. A strike a couple of millimetres off will bind a deadbolt - it is the first of the three common installation mistakes we see, and on a commercial door it becomes a service call. Terry's offers advice and installation across the Gold Coast. For where McGrath sits in the market, see the McGrath brand profile and the commercial specialists in Chapter 10.

McGrath F54 ANSI Mortice Lock - 70mm Backset - FAQ, Fitting and Owner's Guide

Everything below is here to help you choose, fit and live with the McGrath F54 ANSI mortice body. For the whole McGrath mortice range in one place read the McGrath Mortice Locks Guide; for general smart-lock questions see Chapter 13 - Smart Lock FAQ; for measuring your door use the Buyer's Guide, starting at Chapter 02 - backset.

Choosing the Right Body

What does ANSI mean on a mortice lock, and how is it different from the Euro bodies?
ANSI describes the American commercial mortice format: a 70mm backset, a 92mm distance between the spindle and the cylinder (the pitch), a 32mm-wide faceplate and a threaded Kawneer cylinder. The McGrath Euro bodies use an 85mm pitch, a 22mm faceplate and a Euro profile cylinder, so the two formats are not interchangeable in a door even when the backset matches. Our mortice guide explains what a mortice body actually is and where the ANSI pair sits in the range; Chapter 01 covers the mechanical layer under any smart lock.
F05 or F54 - which one should I order?
Order the F54 (this product) only where a mechanical deadbolt is specifically required and the door is not a fire door. For a smart-lock install, a fire door, or any door where a deadbolt would just be disabled anyway, order the F05 - it is the same body without the deadbolt and it is the configuration the fire assessments are written against. The full argument is in which one do you need, with the key difference and what the two have in common.
I am replacing an existing body - how do I identify what I have?
Four steps: count the bolts (a latch alone is the F05 pattern; a latch plus a single straight deadbolt could be an F54 or a Euro 85 body), check for a keyhole, measure the backset (70mm) and measure the faceplate - 203 x 32mm on both ANSI bodies, and the 32mm width is the giveaway because every other McGrath body is 22 or 24mm wide. The whole routine is in how to identify the body you already have, and the heavy-commercial gallery shows the two ANSI bodies beside the 60/68.
My door is prepared at 60mm - can I still use an ANSI body?
No. The ANSI bodies are 70mm backset only, and the case is 99.5mm deep into the door, so a 60mm preparation puts the spindle 10mm out of line with the furniture. What happens when the backset is wrong covers the symptoms. A 60mm ANSI door is unusual in Australia; if your door really does measure 60mm it was almost certainly prepared for a Euro or tubular body - see standard backset sizes and Chapter 02.

Cylinders, Keys and the Mechanical Override

What is a Kawneer cylinder, and why does the Euro cylinder not fit?
A Kawneer-thread cylinder is the screw-in mortice cylinder used on American-pattern ANSI locks: it threads into the lock case rather than being retained by a fixing screw through a Euro profile aperture. The McGrath Euro cylinders in our cylinders and barrels category are the wrong shape for the pocket. This is the most common ANSI ordering mistake; the cylinder note in the ANSI blog has the same warning. Ask us to quote the cylinder and keying with the body - we do not currently list a Kawneer cylinder on its own.
Where is the keyhole on the finished door?
In the Bardon's external escutcheon, 92mm below the spindle - the cylinder sits inside this mortice and the escutcheon has a matching opening. That is why the pitch must be 92mm on an ANSI body: it is the distance from the handle spindle to the keyhole. Our blog on mechanical key override shows where to look on each McGrath model, and what to do when the battery dies. Locks with a backup key are gathered in the has backup key category.

Fire Doors

What exactly was tested, and what FRL did it get?
Jensen Hughes fitted a McGrath Bardon to an F54 ANSI mortice with the 350 x 85mm McGrath scar plate and ran two pilot-scale tests to section 2 and appendix B11 of AS 1530.4:2014 - Firecore (test FRT250547, 17 April 2025) and E-Core (test FRT250885, 7 May 2025), 120 minutes each - then assessed the lockset under AS 1905.1:2015. The headline is FRL -/120/30, with the Firecore report also assigning -/240/30 and -/60/30 to particular reference doorsets. The two master range assessments (Jensen Hughes 120207 Firecore and 119867 E-Core) then carry the Bardon on the F05 ANSI mortice without the deadbolt at -/120/30 across every reference doorset. Our fire certification reference lists them alongside the other assessed locks; how smart locks are tested for fire doors explains the process.
Why does the deadbolt have to be disabled?
Because AS 1905.1 does not permit a bolt that can be left protruding and stop a fire door from closing. Every one of the four assessment reports carries that condition: the FRL is valid only for locksets with the deadbolt function disabled. On the F54 that means taking the deadbolt out of service - on the Bardon the deadbolt is driven from the internal turn snib, and McGrath sells a blank disc to cover the aperture once the snib is removed. Confirm the method with us or LSC before sign-off. The one-penetration rule is the related reason you usually cannot add a separate deadbolt to an apartment fire door.
What does one-way FRL mean for my door?
The batteries sat on the exposed (fire) side in the tested system, so the assessment covers fire attack from the battery side - the interior escutcheon side - only. For most apartment entry doors, where the corridor is the protected side and the unit is where a fire would start, that is the direction that matters, but it is not a both-ways rating. Talk to us or LSC before specifying for a door that must resist fire from either side. How to identify a fire door and finding the compliance tag help you work out what you have.
Do I need the scar plate?
On a retrofit over an existing lock cut-out, yes - the Bardon scar plate is part of the tested assembly, and both master reports state that the no-scar-plate configuration is only for doors with no pre-existing holes. The E-Core test deliberately replicated replacing a redundant hotel card lock with the plate covering the old holes, which is the most common Bardon retrofit. On a new door with no other holes the plate is optional. Browse scar and adaptor plates for the rest of the range.
How long are the assessments valid, and is the door itself covered?
The two Bardon test assessments run to May 2030; the two master range assessments expire in January and October 2029 and depend on third-party doorset certificates staying valid. The assessment covers the lockset; the door, frame, hinges and closer are certified separately, and the opening takes the lowest rating in the set. Read the compliance summary, the strata checklist and the four strata checks before any work on an apartment door, and the asbestos risk windows on older buildings.

Fitting and Operation

Is it handed? Do I need a left- or right-hand version?
No - one body suits either hand. The latch is reversible and the handing is field changeable, so establish the handing first (step by step, and note the US versus Australian convention on an American-pattern lock) and set the latch bevel to face the strike before the body goes into the door. Field-reversible versus fixed explains why this matters at ordering time on other products.
How does the deadbolt work with the smart lock?
The 25.4mm deadbolt is a mechanical bolt inside the case, thrown and retracted through the furniture - on the Bardon that is the internal turn snib and the cylinder from outside. Unlocking the smart lock with PIN, card or app retracts the latch; the deadbolt is a separate mechanical act. Deadbolt projection covers why a one-inch throw matters, and Chapter 02 sets the short and long throws side by side. Remember that on a fire door this function must be disabled.
Any fitting tips?
Set the strike so the deadbolt has clear travel and the latch dead-latches against the strike plate rather than the frame - a strike even slightly high will bind, which is installation mistake number one in our troubleshooting blog, followed by poor door preparation. The case is 99.5mm deep and 22mm wide, so check the mortice pocket before the body goes in. On a commercial or fire door we recommend a locksmith - Terry's advice and installation service covers the Gold Coast.
What door thickness does it suit?
Minimum 45mm - a figure that comes from the F05 side of the range, so confirm with us for the F54 on a thin door. The upper limit is set by the host lock's spindle, not the mortice: the Bardon guide documents ANSI spindle lengths for doors up to 100mm thick, although its data sheet quotes 35 to 55mm as the standard range - see its specifications. Chapter 02 explains how door thickness is measured.

Suitability and Limitations

Which McGrath locks does it suit, and which does it not?
It suits the Bardon - the only McGrath smart lock specified on an ANSI body. It does not suit the A210, A231, A236 or NX5 (85mm-pitch Euro 85 swing or hook bodies), the NX1 or Albion (60/50 spindle mortice), or the NX6 and NX6W (Euro 60/68 three-point). The Windsor, Hamilton and Stafford fire assessments were run with tubular latches and dormakaba MS2602 / MS2902 mortices, not an ANSI body. The five-family table lays this out in one place.
Will it work on a sliding door?
No. Neither ANSI body has a hook bolt and the Bardon is a hinged-door lock. For a sliding or bifold door use the 28mm or 35mm Euro 85 hook body with the A231 sliding-door lock; why a hook instead of a bolt explains the reason. Sliding-door options are gathered under glass sliding door smart locks.
Is there a Lockton or dormakaba equivalent?
Not for the ANSI format. The Lockton E-Series Euro smart mortice bodies are 85mm-pitch Euro bodies that interchange with the McGrath Euro 85 swing range - the SML-H70 shares this body's 70mm backset and nothing else. The dormakaba MS2602 is the 60mm Euro primary mortice the Windsor, Hamilton and Stafford assessments name; it is not an ANSI body and it is not assessed with the Bardon, and matching a dimension is not the same as an approved combination. Our guide's cross-brand equivalents and MS2602 sections keep the two apart.
Is it suitable near the coast?
The case, latch and deadbolt are SS304 stainless steel, which handles a coastal commercial environment well, but McGrath does not quote a salt-spray figure for the mortice bodies and we do not claim one. The exposed part of the installation is the smart lock furniture, so read the host lock's corrosion notes - Chapter 11 on corrosion grades and Queensland considerations.
