The Carbine CDL7100SC-HD is a mechanical digital lockset from the CDL7 Heavy Duty series: a large easy-grip knob and keypad on the external face, a BCA-compliant lever inside, and no batteries, electronics, or connectivity anywhere in the product. Entry is by code on the ball bearing-style push buttons, then turning the knob; the internal lever always operates the latch freely, so exit is single-action with no code - the combination that makes this model suitable for fire and egress doors. If mechanical digital locks are new to you, our guide to how a battery-free keypad lock works covers the coding chamber behind the buttons.
As the heavy duty upgrade of the standard CDL7100, it runs stainless steel cryptographic elements rather than zinc, harder-wearing internal code components, and a cycle test result exceeding 100,000 openings - the build detail our heavy duty commercial guide unpacks. That makes it the workhorse pick for storerooms, key cabinets, plant rooms, and busy retail stockrooms - and its 240-hour salt spray result (C7 High) handles exposed and coastal mounting. The Buyers Guide's commercial mech-digi chapter puts the CDL7 in context against the wider Digital Mechanical Locks range.
Two backsets are available - 60mm standard (CDL7100SCHD) and 70mm (CDL710070SCHD), with 127mm on request - in satin chrome, reversible for left and right hand doors, on doors 32 to 54mm thick. The 58.75mm body covers NK2000 and Lockwood 530 fixing holes, making it a direct retrofit in most Australian commercial installations. Need the door held open for busy periods? The CDL7100-HBSC-HD is this exact lock plus a holdback function.
Exceeds 100,000 cycle openings with stainless steel cryptographic elements - steel where standard mechanical digital locks run zinc. Designed for high-volume commercial environments including storerooms, retail, education, and industrial applications; this is not a light residential product. Our guide to high-traffic keypad locks covers when heavy duty is worth paying for.
Salt spray tested to 240 hours per AS4145.2-2008 and rated C7 (High) - suited to moderate, tropical and industrial or marine environments roughly 100m to 10km inland. Site conditions vary, so confirm suitability for heavily exposed locations, and note finish degradation is excluded from warranty. Carbine's salt spray testing information sheet (PDF) explains the test method, and the Buyers Guide's corrosion grade explainer shows where C7 sits on the AS4145.2 scale.
The internal lever handle meets BCA accessibility requirements - the clearance between the lever and the back plate or door face at the centre grip section is not less than 35mm and not more than 45mm, meeting the operational requirement of AS1428.1. The lever always operates the latch freely - exit is single-action, no code needed to leave. Note the external face is a knob, not a lever - accessibility compliance applies to the internal side.

Code Control
Entry is by code on the external keypad, then turning the knob; the internal lever always operates the latch freely, so exit never needs a code. Changing the code is a genuinely simple job on the HD series: the back cover of the pad lifts off without tools, and the code is set on slider switches - slide each switch to expose the red indicator to include that digit, replace the cover, done. One behaviour worth knowing: after pressing the clear (C) button, digits can be entered in any order - any combination containing the set digits unlocks the lock. Carbine recommend 4-5 digit codes for higher security.
The factory default is C13579 and must be changed - and tested with the door open - before the door is closed on it. The full procedure with figures is in the installation instructions (PDF), and our Carbine slider code-change walkthrough steps it through with realistic timings.

Gate Installations
The CDL7100 is a proven gate performer - the Installation Gallery tab includes a narrow stile gate install at Carrara, and the knob external face suits gates well: nothing to lever on, nothing to snap. The C7 High salt spray rating handles exposed mounting. On a pool barrier, the gate must still self-close and self-latch to meet barrier requirements - the lock provides code control, never a substitute for the barrier's own compliance. The pool gate section of our latch vs bolt guide covers the setup rules.
For gate posts and narrow frames, the Carbine Gate Guard for CDL7 (mounting box) adapts the lock to gate frames - see its specification sheet (PDF) and installation instructions (PDF). The Buyers Guide's gate keypad locks chapter covers stile widths, latch types, and exposure; if a code is wanted from both sides of the gate, our double-sided gate locks guide explains the options.

CDL7 HD Series - Product Family
Four heavy duty configurations share the CDL7 platform - the differences are handle type, holdback, and how many keypads. Our three-brand comparison covers where the CDL7 sits against Lockwood DX and Borg equivalents.
All models satin chrome. HD series runs stainless steel cryptographic elements and exceeds the 100,000 cycle test. Need the door held open during busy periods? The CDL7100-HBSC-HD adds a holdback function to this exact lock - our holdback mode explainer covers when it earns its keep. Need dual-sided lever accessibility? That is the CDL7200LL-HD.

Fire Rating - When and How It Applies
The CDL7100SC-HD is genuinely fire-door suitable: the internal lever always operates freely, giving the single-action egress fire doors require, and the lock achieves FRL -/120/30 under AS1530.4:2014 and AS1905.1:2015 with the supplied 60mm tubular latchset on a tested Firecore or E-Core doorset. All other assembly hardware - hinges, seals, closers - must also be fire rated for the specific door system.
The certification trail: Warringtonfire assess the CDL7100 series on E-core doorsets in report FAS220275 (Table 10, pages 13-14 - both the CDL71/CDL7100 series line and the combined CDL7100 & CDL7200 line) and on Firecore doorsets in report FAS220387 (Table 9, page 10), with the CDL7100's CSIRO opinion in Certificate of Assessment 2374 (PDF). The two Warringtonfire reports are doorset-specific and not interchangeable across core types.
Our guide to reading fire certification documents explains how to match a report to your actual door, the Buyers Guide's fire door core types chapter covers what E-core and Firecore mean, and our apartment fire door compliance guide explains FRL ratings and what certifiers look for. Browse everything we carry for those doors in the Fire Door category. As always, confirm the full doorset with your certifier before specifying.
Frequently Asked Questions
Yes - with the supplied latchset on a Firecore or E-Core fire-rated doorset, achieving FRL -/120/30 under AS1530.4:2014 and AS1905.1:2015. The always-free internal lever gives the single-action egress fire doors require. All other hardware in the assembly - hinges, seals, closers - must also be fire rated for the specific door system. See Fire Rating above for the certification detail.
Remove the rear cover of the lock body - no tools needed on the HD series, the back cover lifts off. The code is set on slider switches: slide each switch to expose the red indicator to include that digit, then replace the cover. The factory default C13579 must be changed before installation, and tested with the door open. Our Carbine code-change walkthrough covers it step by step.
Yes - order item code CDL710070SCHD for the 70mm version; the 127mm backset is also available on request. Not sure what your door needs? Our backset measuring guide takes a minute.
The CDL7100-HBSC-HD adds a holdback button to the internal lever - press it and the latch retracts and holds open for free passage during busy periods. This standard model does not include that function; everything else is identical. Our holdback mode explainer helps you decide if it is worth having.
It achieves 240-hour salt spray (C7 High), indicating suitability for moderate/tropical and industrial/marine environments roughly 100m to 10km from the coast under AS4145.2-2008. That said, exact site performance cannot be guaranteed without knowing the installation conditions, and finish degradation from salt or chemical exposure is excluded from warranty. For heavily exposed coastal sites, confirm suitability with us before specifying - and plan on a regular freshwater wipe-down.
Additional Information
Fire door installations: Fire rating applies only when installed with the supplied 60mm tubular latch on a tested Firecore or E-Core doorset, and all hardware in the assembly must be independently fire rated. Our apartment fire door compliance guide covers what certifiers check.
Code change before installation: The factory default C13579 must be changed and tested before fitting - test with the door open. After the clear (C) button is pressed, digits can be entered in any order; any combination containing the set digits unlocks the lock. Carbine recommend 4-5 digit codes. Our code change guide's test-five-times rule exists for exactly this moment.
Retrofit compatibility: The 58.75mm body covers NK2000 and Lockwood 530 fixing holes. Confirm the existing hole pattern against the supplied template before retrofitting. Our guide to retrofit kits and spare parts covers why serviceable hardware matters over a lock's life, and the Buyers Guide's door measuring chapter covers what to check first.
Salt spray rating context: The 240-hour C7 result is a laboratory test - continuous direct salt spray in a closed booth, far more aggressive than an installed lockset sees in the field. C7 indicates suitability under categories C2.3 (moderate/tropical) and C2.4 (industrial/marine, 100m-10km from coast). Finish degradation is excluded from warranty regardless of rating; a regular freshwater wipe-down keeps the satin chrome presentable, and the mechanism stays covered for the full 10 years.
Warranty
Carbine is a Davcor Group brand, and Davcor backs its mechanical digital locks with one of the longest warranties in the category: 10 years against defects in materials and workmanship from the date of original purchase. There are no electronics or batteries in this lock to shorten the cover - the whole product is warranted for the full term.
On a valid claim, Davcor will repair the lock, replace it, or supply an equivalent product. Keep your proof of purchase, and make the claim as soon as a defect becomes apparent.
What the warranty does not cover: fair wear and tear; damage caused by faulty installation, misuse, or modification of the product; and tarnishing or change to the finish from weather, salt, or chemical exposure. On coastal and exposed sites, regular cleaning of the finish is the practical answer - the lock mechanism itself remains covered.
Our goods come with guarantees that cannot be excluded under the Australian Consumer Law. You are entitled to a replacement or refund for a major failure and compensation for any other reasonably foreseeable loss or damage. You are also entitled to have the goods repaired or replaced if the goods fail to be of acceptable quality and the failure does not amount to a major failure.

Carbine CDL7100SC-HD - Deeper Questions
The code lives in mechanical slide switches behind the external pad, so it can only be read or reset with the lock accessible - normally with the door open. Since the inside lever is always free, you can still get out; getting back in without the code is a locksmith visit. Record the code somewhere secure the day it is set.
After pressing the clear (C) button, the set digits can be entered in any order - any combination containing them unlocks the lock. It is a characteristic of the mechanical coding chamber, not a fault, and it is why Carbine recommend 4-5 digit codes for higher security. Our guide to how mechanical digital locks work explains the mechanism.
A competent DIYer with the right tools can: the instructions call for a chisel, a 25mm spade bit, an 8.5mm drill bit, and a Phillips head screwdriver, and the box includes the drilling template. The bevelled latch bolt must face the direction the door shuts - the instructions (PDF) diagram it. If the door is a fire door, installation must not compromise the fire-rated doorset - that is a job for a competent installer. We install across the Gold Coast; the Installation Gallery tab shows our work.
In most cases, cleanly - the 58.75mm body footprint is designed to cover the fixing hole pattern both leave behind. Confirm the existing hole pattern against the supplied template before committing to a retrofit without a scar plate, and check your backset (how to measure) to pick the 60mm or 70mm item code.
No - this is a pure keypad lock: PIN entry outside, free lever inside, no key cylinder. No keys to cut, lose, or control; the discipline is guarding the code. If your application genuinely needs a key path, talk to us before ordering.
Gates yes - the gallery includes a narrow stile gate at Carrara, and the Gate Guard mounting box adapts the lock to gate frames. On a pool gate, the barrier must self-close and self-latch to meet barrier rules. The pool gate section of our latch vs bolt guide covers the requirements.
The lock is reversible for left and right hand doors - the handles are handed during installation per the figures in the installation instructions (PDF). Check your door's handing first; the Buyers Guide's handing explainer shows how.
Pick the holdback CDL7100-HBSC-HD if the door genuinely lives in two modes - held open for deliveries or shift change, code-controlled otherwise. If the door stays code-controlled all day, this standard model does everything else identically, costs less to specify, and adds the 70mm backset option the holdback variant lacks off the shelf.
All three are quality mechanical digital platforms - Lockwood's DX range converts existing mortice locks, Borg leads on marine-grade finishes and on-door code changing, and the Carbine CDL7 HD is the heavy duty commercial pick with its stainless internals and fire-door certification trail. Our Lockwood vs Borg vs Carbine comparison puts them side by side, and the Buyers Guide's three-brand chapter goes deeper.
