Description
CompX National Disc Tumbler Cam Lock For Cabinets
CompX National disc tumbler cam lock gives drawers and cabinet doors a keyed security point using a 1-3/16 inch cylinder with 90 degree clockwise rotation, so you get a consistent throw angle that matches common cam lock layouts in woodworking projects. The flat black finish on this C8053-C420A-Y21 lock provides a neutral appearance that blends with darker furniture and fixtures, supporting clean visual lines on casework. Stock keying on this 8053KA-420 cam lock follows CompX National options of keyed alike, keyed different, or keyed different and master keyed, so shop standards can align with your preferred key-control system. Each lock uses a disc tumbler mechanism, which creates a defined key profile for this series and supports predictable operation across similar installations. Key removal in both locked and unlocked positions allows installers to position cylinders and cams without holding the key.
Cam Lock Details That Support Cabinet Projects
- The 1-3/16 inch cylinder length establishes the maximum combined front and frame thickness in overlay applications, so project layouts can be planned around the stated dimension.
- Supplied stop washer allows the cam to turn 90 degrees, giving a clear quarter-turn action that helps align latch points with strikes or frames during layout.
- Cams for lipped or overlay construction use a straight cam with 1-1/2 inch extension, so the locking tab can reach behind a face frame or lip in typical cabinet designs.
- Cams for flush construction use a formed cam with 1-1/8 inch extension and 11/32 inch offset, letting the cam engage a strike or frame set back from the front surface.
- Key removable in both locked and unlocked positions lets you set cylinder orientation and confirm cam position while installing multiple units on a run of casework.
Cam Lock Installation And Overlay Application Notes
CompX National cam lock 1-3/16 cylinder length sets the limit for overlay applications where the combined thickness of front and frame cannot exceed that dimension, so panel build-ups are chosen to stay within the stated capacity. For an overlay construction using a 3/4 inch front and a 3/4 inch frame, CompX National specifies using an NLC8053 lock body combined with the NLC7014-2C cam, which gives installers a defined pairing when working at that total thickness. The provided stop washer creates the 90 degree clockwise rotation, so the cam travel can be predicted when positioning strikes or frame contacts. Trim washer, spur washer for wood, and mounting nut give mounting interfaces for typical cabinet materials, allowing the cylinder to be secured to both wood fronts and other casework panels.
Using This Cam Lock In Drawer And Door Builds
Where This Flat Black Cam Lock Is Applied
This flat black disc tumbler cam lock is specified for drawers and for right-hand or left-hand doors, so a single lock style can be used across mixed casework on the same project. The cams for lipped or overlay construction, using the straight cam with 1-1/2 inch extension, let the lock engage the back of an overlay or face frame in common cabinet layouts. For flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset positions the locking surface behind a flush front, aligning with partitions or frames that sit directly in the cabinet plane. Stock keying defined as KA, KD, or KDMKD means all keyed alike, all keyed different, or all keyed different and master keyed, giving shops options for grouping locks on banks of drawers or doors.
Details That Help Repeatable Lock Installation
The 90 degree clockwise rotation created by the stop washer keeps the key turn and cam throw consistent from unit to unit, which supports repeatable layouts when drilling multiple fronts. Key removable in both locked and unlocked positions lets installers set all cylinders to the same key orientation before final tightening, helping maintain a uniform appearance across a cabinet run. The disc tumbler construction defines the keyway used on this C8053-C420A-Y21 model, so keys from this series operate locks specified with the same stock keying choice. Trim washer and spur washer for wood create a stable bearing surface on the front panel, helping resist rotation of the cylinder in wood applications when the cam loads against a frame. Unassembled REMOVACORE versions are available, which lets users work with core-changeable variants when job requirements call for that style of lock management.
Common Questions About This CompX Cam Lock
