Borg BL4401MGPRO Marine Grade Pro Mechanical Digital Gate Lock - Lever/Lever - Black
At A Glance
The Borg BL4401MGPRO (BL4401 MG Pro) is a fully mechanical digital lock in a lever/lever configuration, built for external wooden and timber gates and doors. The external lever free-turns until the correct PIN is entered, then engages to retract the 60mm anti-thrust tubular latch; the inside lever is always free, so exit is immediate with no code. It shares the free-turning lever keypad of the BL3400 gate series and the BL2600 series footprint, in Marine Grade Pro construction - 316 stainless steel internals under Borg's MG Pro black marine coating, salt spray tested to 1,000 continuous hours.
This is the standard (non-ECP) chamber: the code is set On The Bench by arranging red coded and blue uncoded code pieces, which delivers over 8,000 combinations with a code length of 3 to 7 digits - but changing the code means taking the lock off the gate. If you expect to change codes often, the BL4401MGPROECP does the same job with on-gate Easicode Pro code change. Borg's letter soup decoded: MG Pro and ECP explained.
The BL4401 accepts gates and doors from 35mm to 80mm thick, is reversible on site for left or right hand swing, and needs no batteries, wiring or power at any point. New to battery-free keypad locks? Start with what a mechanical digital lock is and Chapter 16's gate lock guide.
Usually ships same day if ordered before 11am AEST (excludes weekends and Queensland public holidays).
No code is ever needed to get out: the inside lever turns freely at all times, and the anti-thrust latch self-latches when the gate closes behind you. This is what makes the single-sided BL4401 the usual pick for any gate where people must be able to leave without thinking - on a pool barrier gate, a compliant self-latching gate latch still has to do the barrier's job (see the FAQ). If your gate is open-topped and a free inside handle could be reached over from outside, look at the back-to-back BL4441 instead - our double-sided gate lock guide explains the trade.
The holdback function lets the inside lever be held in the open position for free through-passage during deliveries, working hours or open-house periods, and it is removable if you never want the lock left on the latch. On a pool barrier gate, only use holdback while a compliant self-latching gate latch (such as a MagnaLatch) is fitted and doing the barrier's self-latching job - this lock's own latch never does that job. Never rely on holdback for a fire or egress door. The mode is explained in passage mode vs holdback mode.
316 stainless steel internal components with the MG Pro black marine external grade coating, salt spray tested to 1,000 continuous hours. Suitable for coastal, beachside, canal-front and marine environments. The 1,000 hours is a laboratory cabinet result (the finish held up that long in continuous salt fog), not a promise of service life on the coast. For what those salt spray hours actually mean, see MG Pro and ECP explained and the honest three-brand corrosion comparison.
Borg warrants corrosion resistance for 12 months from date of sale under specified conditions - a claim most external keypad locks do not make at all. Keep up the simple routine in the Borg Servicing Guide (see the maintenance notes) for the best long-term result.
The BL4401MGPRO uses Borg's On The Bench code system. To change the PIN the lock comes off the gate: the cover plate is removed and the red (coded) and blue (uncoded) code pieces are rearranged with the supplied tweezers. Code length is adjustable from 3 to 7 digits with the spare code pieces provided, giving over 8,000 combinations. The full procedure is in the Non-ECP Code Change Instructions (PDF) and our On The Bench method walkthrough. For on-gate code change without removal, see the BL4401MGPROECP.
Entirely mechanical. No power source, no wiring, and no battery maintenance at any point - nothing to go flat on a side gate you rarely think about.
The BL4401 MG Pro holds one active PIN at a time. There is no audit trail and no per-user codes - the honest trade-off of every mechanical digital lock, covered in the category's limitations.
For heavy duty, consider the Lockwood 3572DX, Borg BL7701, or Carbine CDL7200 - our heavy duty guide explains what separates them.
Installing on a narrow aluminium gate frame?
The BL4401MGPRO ships as standard with a 60mm backset tubular latch, which will not fit a narrow 50mm x 50mm aluminium gate frame. You can still fit this lock to a narrow-stile frame - order the matching 28mm backset latch below and use it in place of the standard 60mm latch that comes in the box.
The 28mm latch is handed and cannot be reversed, so confirm which way the gate opens as well as the frame size - see Accessories and Spares. Not sure which stile width you have? See our Gate Post Too Narrow for a 60mm Latch guide.

Frequently Asked Questions
Code changes require removing the lock from the gate. With the keypad face-down on a flat surface, remove the two red cover plate screws (take care - the plate has springs attached). Press and hold the C button, then use the supplied tweezers to rearrange the red coded and blue uncoded code pieces to set your new combination. Replace the cover plate, refit the lock, and test the new code several times before closing the gate. The code can be 3 to 7 digits using the spare code pieces provided - full steps in the Non-ECP Code Change Instructions (PDF). For on-gate code change, see the BL4401MGPROECP.
The lock's job is access control, not the barrier's self-latching function. Our site-wide position is straightforward: a bolt-format lock is never allowed on a pool barrier gate because a bolt does not secure anything until it is thrown, but a self-latching latch lock like this one is fine so long as a genuinely compliant self-latching gate latch (such as a MagnaLatch) is doing the barrier's self-latching job. The inside lever is always free for egress. Holdback is only acceptable on a pool barrier gate while that compliant gate latch is fitted and doing the self-latching - this lock's own holdback is an access-control convenience, not a barrier safety feature (see holdback on pool barrier gates). See the full pool safety barrier gate treatment in our latch vs bolt guide, and get final sign-off from a licensed pool safety inspector before you specify any lock for a pool gate.
The BL4401 MG Pro is designed for wooden and timber gates. On a narrow aluminium frame (50mm x 50mm or similar), the 60mm tubular latch will not align - you need the handed 28mm backset latch (left hand / right hand). For purpose-built metal box-section gates, consider the forend-fixing BL3400 or back-to-back BL3430 series instead - measure first with our narrow stile guide.
The BL4401MGPRO (this model) uses the On The Bench code system, which offers over 8,000 combinations because the code length can be set anywhere from 3 to 7 digits. The BL4401MGPROECP uses the Easicode Pro push-button system - non-sequential (the coded buttons open the lock in any order of pressing) with over 4,000 combinations. Both are strong for residential and light commercial use; the practical difference is how the code is set and changed, and whether the lock has to come off the gate to do it. See changing codes on mechanical digital locks.
Pick by three questions. Will the code change often? If yes, go ECP (BL4401MGPROECP); if rarely, this On The Bench model gives more combinations for less money. Can someone reach over the gate to the inside handle? If yes, the back-to-back BL4441 closes that gap. Is the stile too narrow or hollow to bore for a tubular latch? Then the rim-fixed BL4409 face-mounts with no boring. Chapter 16's Borg naming decoder helps too.
Additional Information
The On The Bench system requires the lock off the gate for a code change - so set and confirm your code on the workbench before installing. It is far easier than removing a fitted lock for the first change. Test the new code 3 to 4 times on the bench before fitting, and record it somewhere secure - there is no key override on this model.
Monthly: wipe the keypad, both levers and the exposed latch with a light spray of silicon-based lubricant (such as GT85) and remove the excess with a soft cloth. Do not use oil-based lubricants such as WD-40 - they attract dirt and wear down internal parts over time. Annually: remove the lock from the gate, spray the inside through the code piece holes on the reverse of the keypad with silicon-based lubricant, spray all fixings, accessories and the latch with silicon-based lubricant, then press each button and operate both levers several times to confirm smooth operation. The MG Pro coating resists salt attack; it does not exempt the lock from this care. Full steps are in the Borg Lock Servicing Guide (PDF).
The 60mm backset tubular latch is in the box; 50mm and 70mm backsets are available separately, and 50mm aluminium frames need the handed 28mm latch instead. Confirm the correct backset before installation - our stile measuring guide takes two minutes and saves a second site visit. Note the handed 28mm latches are not field-reversible - see understanding door handing.
The BL4401 uses lever handles on both sides rather than a knob. A lever needs less grip force and torque, which suits heavier or outward-opening gates and users who find a knob difficult to turn. For a knob-style keypad in the same marine grade family, see the Borg BL2601 MG Pro.
The matching spare keypad for this lock is the BL4401KMGPRO (standard chamber with On The Bench code change, like this lock). The BL4401KMGPROECP is the Easicode Pro keypad for the same platform - a path to on-gate code change. The letters matter: MG Pro and ECP explained decodes Borg's naming in two minutes.
Warranty
All Borg locks are warranted against mechanical defects in materials and workmanship under normal use and service for a minimum of 12 months from date of sale. The warranty does not cover damage arising from misuse, vandalism, or improper installation. The lock must not be dismantled - doing so will invalidate the warranty. Proof of purchase required for all claims.

Borg BL4401 MG Pro - FAQ and Owner's Guide
Everything below is here to help you choose, install, code and live with the BL4401 MG Pro gate lock. For the wider category, see Chapter 16 - Mechanical Digital Locks in the Buyer's Guide.
Choosing the Right BL4400
MG Pro is Borg's Marine Grade Pro tier - 316 stainless internals, MG Pro black marine coating, 1,000 hour salt spray testing. ECP (Easicode Pro) is the on-gate code change system, and this model deliberately does not have it: it uses the standard chamber (On The Bench code change) instead, which trades code-change convenience for a higher combination count (8,000+ vs 4,000+) and a lower price. The full decoder ring is in MG Pro and ECP explained and Chapter 16's Borg naming guide.
No. If the gate is open-topped and the free inside lever is within reach from outside, the keypad is defeated in seconds. That situation is exactly what the back-to-back BL4441 exists for - keypads both sides, code required in both directions. The trade-off (no free egress) is explained in the double-sided gate lock guide.
Two paths. If the frame is a 50mm aluminium section, keep this lock and swap to the handed 28mm backset latch (LH / RH). If boring the stile is off the table entirely, the rim-fixed BL4409 slam latch face-mounts with no boring at all. The four narrow-stile answers compare every option.
Not recommended - this platform is rated light to medium duty. High-traffic doors chew through light-duty clutching mechanisms. Step up to the Lockwood 3572DX, the Borg BL7701 or the Carbine CDL7200 - the differences are in the heavy duty commercial guide.
Codes and the On The Bench Code Change
Behind the keypad sits the coding chamber, loaded with code pieces - red ones are coded (part of your combination), blue ones are not. Rearranging which positions hold red code pieces sets the code, and because you can run anywhere from 3 to 7 coded digits, the combination space exceeds 8,000. It is the same shared bench method used across Borg's standard chambers - our bench method walkthrough shows it step by step with realistic times.
There is no key override, so a forgotten code with the gate closed means locksmith attendance or lock removal. Record the code securely when you set it, and always test a new code several times with the gate open. On the plus side, the free inside lever means you can never be locked IN - egress is always available.
For casual entry control, yes - over 8,000 combinations defeats guessing, and the anti-thrust latch resists carding. But be honest about the limits: one code shared by everyone, no audit trail, no wrong-attempt lockout, and anyone who learns the code keeps it until you change it On The Bench. If you need per-user codes, schedules or logs, that is electronic lock territory - the trade-offs are covered in the honest limitations.
Coastal Environment and Maintenance
Marine Grade Pro is Borg's top corrosion tier: 316 stainless steel internals under the MG Pro coating, tested to 1,000 continuous hours of neutral salt spray - many external-grade locks test to a fraction of that. On beachfront, canal-front and salt-air installs the difference is the whole game: see what the salt spray numbers mean and the honest three-brand corrosion comparison.
Monthly: a light spray of silicon-based lubricant (such as GT85) over the keypad, both levers and the exposed latch, excess wiped off - never WD-40 or other oil-based lubricants, which attract dirt. Annually: a full service - the lock comes off the gate, the inside is sprayed through the code piece holes on the reverse of the keypad, and every button and both levers are cycled to confirm smooth operation. Ten minutes a year is the difference between a lock that lasts and one that sticks - full steps in the Borg Servicing Guide (PDF).
Yes - Borg warrants corrosion resistance for 12 months from date of sale under specified conditions, alongside the standard 12 month mechanical warranty. Most lock brands exclude coastal corrosion outright, so this is worth noting. Bought from us? We manage the claim with the Australian distributor for you.
Installation and Fit
35mm to 80mm - the supplied fixing screws and the 8mm flat bladed sprung spindle cover that range. If your gate falls outside it, talk to us before ordering rather than improvising fixings. The self-latching action relies on a square-hung gate, so fix any hinge sag before install day.
The lock itself is reversible on site for left or right hand swing, so a re-hung gate is not a problem. The exception is the 28mm narrow-stile latch for aluminium frames, which is handed and not field-reversible - pick left or right hand at order time. Unsure which is which? See understanding door handing in Australia.
Close to it. The BL4400 series shares the BL2600 footprint and uses the free-turning lever keypad of the BL3400 gate series, so an installer familiar with either platform will recognise the drilling pattern and fitting sequence. The tubular latch bores like any 60mm backset latch.
Usually not. Magnetic gate latches paired with mechanical keypads have a high callback rate - misalignment and gate sag cause the magnet to grab before the keypad releases. If your stile genuinely cannot take the 60mm or 28mm latch, read why magnetic latches can be problematic before ordering the TML25DGT, and talk to us.
Spares and Alternatives
Yes - that is one of the quiet advantages of this range over hardware-store imports. The BL4401KMGPRO spare keypad is the matching standard-chamber (On The Bench) unit for this lock. Latches, fixing packs and post kits are all stocked separately too - see the spare parts argument.
The BL4401KMGPROECP Easicode Pro keypad fits the same BL4400 platform, giving you the on-gate code change of the ECP models without replacing the whole lock - ask us to confirm fit for your unit before ordering. If you are still choosing, buying the complete ECP lock up front is the cleaner path.
Within Borg, the knob-handed BL2601 MG Pro suits standard doors, and the metal-gate BL3400 MG Pro ECP is purpose-built for box-section frames. Chapter 16's three-brand comparison ranges wider across Lockwood and Carbine.
