CompX National Disc Tumbler Cam Lock, 1-3/16" Cylinder with 90 Degree CW Rotation, Flat Black C8053-C642A-Y21

CompX National Disc Tumbler Cam Lock Function

CompX National disc tumbler cam lock delivers a locking cylinder that controls a rotating cam, so you can secure drawers and cabinet doors where a compact, rotary lock is needed. The 1-3/16 inch cylinder length provides a defined reach through the front material, which matters when matching the lock body to panel thickness on woodworking jobs. A 90 degree clockwise rotation of the cylinder turns the cam, giving a short, predictable throw that suits typical drawer and door applications. Flat black finish on the lock presents a dark, low-profile appearance, which helps the hardware blend with darker casework. Disc tumbler construction creates the locking action inside the cylinder, so the key interacts with internal tumblers rather than a simple warded mechanism. This CompX National model is designed as a cam lock, so it becomes the pivoting element in your overall cabinet or fixture locking layout.

Key Lock Details That Support cabinet Work

• The 1-3/16 inch cylinder length defines how far the lock extends through the front, so you can match it to the combined thickness of the front and frame in a cabinet or fixture.
• 90 degree clockwise rotation of the cylinder sets a short, repeatable cam swing, which simplifies planning for the locked and unlocked positions on drawers and doors.
• Key removable in both locked and unlocked positions lets the user remove the key after turning to either state, which can speed cabinet access when frequent locking changes are needed.
• Flat black finish on the cam lock body provides a dark surface, which helps the hardware visually coordinate with black or dark-toned cabinetry and fixtures.
• C8053-C642A-Y21 manufacturer part number specifically identifies this CompX National model, which helps match field replacements or repeat orders to existing installations.

Cam Lock Mounting And Front Thickness Planning

The stated cylinder length defines how this cam lock interacts with the front and frame stack-up in cabinet work. For overlay application, the combined thickness of front and frame cannot exceed the cylinder length listed, so the 1-3/16 inch dimension drives layout choices when you build overlay doors. This model is intended for drawers and for right-hand or left-hand doors, which means the same basic body can be oriented for either swing, simplifying layout across a run of casework. When a project uses a 3/4 inch front and a 3/4 inch frame in overlay construction, the information specifying the NLC8053 lock and NLC7014-2C cam describes an alternative combination that fits that thicker stack. Using the cylinder length and overlay limitation together allows you to align the lock face properly with the finished front while still engaging the cam behind the frame.

Using This CompX Cam Lock In Cabinet Projects

Applications On Drawers And Cabinet Doors

This CompX National disc tumbler cam lock is described for drawers and for right-hand or left-hand doors, so it suits a range of basic cabinet locking points. The same lock body serving both door handings allows a single model to be used across multiple openings on a project. Cams are described for lipped or overlay construction with a straight cam at 1-1/2 inch extension, so the cam reach can address overlay fronts that stand proud of the case. A formed cam at 1-1/8 inch extension with 11/32 inch offset is described for flush construction, so the offset brings the locking surface into line with a flush door or drawer front. These cam options allow the lock cylinder to stay in the same relative position at the front while the cam geometry adapts to different cabinet build styles behind the front.

Details That Influence Fit, Throw, And Workflow

Each lock is described with a stop washer that allows the cam to turn 90 degrees, so the motion is limited to a quarter-turn for consistent locking and unlocking. This defined 90 degree clockwise rotation reduces guesswork when positioning the strike or keeper behind the cam. The trim washer, spur washer for wood, and mounting nut referenced in the description support securing the cylinder in wooden fronts, so the lock can stay firmly seated during repeated use. The spur washer for wood adds bite into the substrate around the cylinder hole, which helps resist rotation of the lock body when the key is turned. Key removable in both locked and unlocked positions means the user can operate the lock and then withdraw the key at either setting, which can streamline access patterns in busy environments. Stock keying descriptions KA, KD, and KDMKD define whether locks are keyed alike, keyed different, or keyed different with a master key feature, so the key system can be selected to match security grouping and control needs across multiple openings. REMOVACORE versions are described as available, indicating that a removable core option can be used where field-changeable keying is part of the project requirements.
