Cam Locks and Cupboard Locks Australia

Ordering the right cam locks and cupboard locks australia joiners, strata managers, electricians, and office fitout contractors rely on requires matching exact material thicknesses, mounting hole shapes, and cam bar offsets. Whether you are replacing a snapped strata letterbox lock in a 2mm powder-coated aluminium faceplate, securing an 18mm melamine office filing cabinet, or fitting recessed flush bolts to the inactive leaf of a commercial double door, this trade measurement guide ensures you select the right hardware on the first order.

Cam Locks and Cupboard Locks Australia: How to Measure Barrel Length

The most common mistake when ordering cam locks and cupboard locks australia wide is measuring the overall length of the lock including the front chrome bezel and rear screw thread. To measure cam lock barrel length accurately like a trade locksmith, place your steel ruler directly behind the flat underside of the front head flange and measure straight back to the rear face of the threaded body (where the rotating metal cam tailpiece sits), excluding both the front head flange and the rear fixing screw.

Standard Australian Cam Lock Barrel Sizing Chart (18mm x 16mm Double-D Cutout):
• 11mm to 16mm Barrel Depth (Suiting 1mm-10mm Material Thickness): Standard for sheet-metal strata letterboxes, steel electrical distribution enclosures, server racks, and thin toolboxes.
• 22mm Barrel Depth (Suiting up to 16mm Material Thickness): Suits medium-gauge marine hatches, acrylic display doors, and 12mm-16mm plywood panels.
• 28mm to 32mm Barrel Depth (Suiting 18mm-24mm Timber / Melamine): Mandatory when drilling through standard 18mm Australian commercial melamine office cupboards, reception desk drawers, and solid timber joinery doors.

Keyed Alike Cabinet Cam Locks vs Keyed to Differ (KD) & C4 Pin-Tumbler Models

Once you measure cam lock barrel length, your next choice is key management across multiple cupboards or lockers. Standard wafer-tumbler keyed alike cabinet cam locks (such as Carbine and CompX National factory KA packs) are pre-cut to a common trade key code so maintenance staff, nurses, or retail managers can unlock twenty display cabinets or electrical meter doors using a single small wafer key with zero extra pinning cost.

Conversely, if you are fitting strata apartment letterboxes where each unit resident must have a unique private key, select Keyed to Differ (KD) cam locks. For high-security commercial joinery, medical drug cupboards, or cash drawers that must integrate with your building's primary house or master key system, choose heavy-duty C4 5-pin or 6-pin brass cylinder cam and cupboard locks from our Cupboard and Furniture Locks collection, which can be pinned alongside your door locks via our Custom Keyed Alike Service (SKU: KA).

Sliding Glass Showcase Locks, Plunger Locks & Rim Cupboard Deadbolts

Beyond round 18mm Double-D cam locks, our cam locks and cupboard locks australia range includes no-drill ratchet showcase locks (which clamp onto the overlapping edge of 4mm to 8mm toughened glass retail display sliders), spring-loaded push-plunger locks that deadlock overlapping timber or metal filing cabinet doors with a single push of the thumb, and surface-mounted square cupboard deadbolts for heritage timber wardrobes and under-stair storage doors.

Commercial Double Door Flush Bolts: Edge vs Face Mounting

Whenever a commercial office, boardroom, or residential patio features a pair of double hinged doors, the primary mortice lock or deadlatch on the active leaf is only secure if the inactive leaf is anchored rigidly into the top head frame and floor threshold using commercial double door flush bolts. Without flush bolts, forcing both meeting stiles inward pops the latch bolt out of the strike keeper even when locked.

When installing commercial double door flush bolts from our Non-Locking Handles & Hardware hub, always mortice a 150mm or 200mm lever-action flush bolt into the concealed vertical meeting edge of the inactive door leaf (at 1,800mm height for the top bolt and 150mm-300mm above the floor for the bottom bolt) so the bolts cannot be flipped open while the active door is locked shut. Pair the bottom floor bolt with a spring-loaded stainless steel dust-excluding floor socket so dirt and gravel never prevent full 15mm bolt throw, and review our Commercial Fire & Meeting-Stile Astragal Seal Guide.
