CompX National Disc Tumbler Cam Lock, Antique Brass with 1-3/16" Cylinder, C8053-C390A-4G

CompX National Disc Tumbler Cam Lock Function

CompX National disc tumbler cam lock is a cam lock in antique brass with a 1-3/16 inch cylinder, so it provides a compact keyed locking point where a short cylinder length is required. The lock uses a disc tumbler mechanism, which provides a defined keying system for controlled access in cabinetry or similar applications. The antique brass finish gives the lock a traditional appearance, which helps it blend into projects using warm-toned decorative hardware. The manufacturer part number C8053-C390A-4G identifies this specific configuration, which matters when matching locks across multiple cabinets or reordering the same setup. This lock is part of the cam locks product class within locks and latches, so it is suited to flat panel doors, drawers, and similar closures that accept a rotating cam to secure the front.

Cam Lock Details That Support Real Projects

• Key removable in both locked and unlocked positions means the key can be taken out after locking or after opening, which helps when multiple operators need access without leaving the key in the cylinder.
• Designed for drawers and for right-hand or left-hand doors, so a single lock style can be applied across mixed cabinet layouts, simplifying planning and standardizing parts on the job.
• A straight cam with 1-1/2 inch extension is used for lipped or overlay construction, giving extra reach behind an overhanging front so the cam can still catch the frame securely.
• A formed cam with 1-1/8 inch extension and 11/32 inch offset is used for flush construction, positioning the cam so it lines up with a flush frame surface without adding extra shims.
• For overlay application, the combined thickness of front and frame cannot exceed the listed cylinder length, which helps determine whether the 1-3/16 inch cylinder suits the door and frame build-up.

Cam Lock Installation And Cylinder Fit Considerations

The 1-3/16 inch cylinder length defines how thick the front and frame can be in overlay use before the threads and cam engagement become too short, so matching this dimension to panel build-up is a key planning step. For overlay applications, the requirement that combined front and frame thickness cannot exceed the listed cylinder length helps determine when this model fits a cabinet without altering the construction. The presence of a spur washer for wood in the supplied components is intended to bite into wooden material, which helps resist rotation of the cylinder during tightening on wood doors or drawers. A trim washer in the supplied parts provides a finished bearing surface around the cylinder, which helps the face of the lock sit neatly against the door or drawer front.

Using This Antique Brass Cam Lock In Work

Where This Cam Lock Fits Cabinet Projects

This cam lock is specified for drawers, so it can secure pull-out storage where a rear catch surface is available for the cam swing. The same lock is specified for right-hand or left-hand doors, which allows the installer to use one model throughout a run of cabinets regardless of door swing. For lipped or overlay construction, the straight cam with 1-1/2 inch extension reaches behind the overlay front, so it can engage a frame or strike that sits inboard of the door edge. For flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset positions the cam face closer to the frame plane, so it aligns with a frame surface that is even with the door front. In overlay scenarios, the statement that the combined thickness of front and frame cannot exceed the listed cylinder length means the 1-3/16 inch cylinder is suited to relatively moderate build-ups, such as many cabinet fronts.

How Design Details Support Consistent Locking Results

The key removable feature in both locked and unlocked positions allows the key to be withdrawn after locking or after opening, so users do not need to leave the key in place and can move between cabinets efficiently. Stock keying options KA, KD, and KDMKD are described in the product data, so projects can be planned with all locks keyed alike, all keyed different, or keyed different with a master key option for controlled master access. The mention that REMOVACORE versions are available indicates that a removable core variant exists in this family, which can matter on facilities that change cores as staff or security needs change. The availability of cams for both lipped/overlay and flush construction means the locking action can be tuned to different cabinet face conditions, supporting consistent engagement without modifying door or frame geometry. The requirement that overlay front and frame thickness stay within the cylinder length helps maintain proper thread engagement on the mounting nut, which supports stable cam alignment over repeated locking cycles.
