CompX National Disc Tumbler Cam Lock, Flat Black with 1-3/16" Cylinder, C8053-C413A-Y21

CompX National Disc Tumbler Cam Lock Function

CompX National disc tumbler cam lock provides keyed security for drawers and right-hand or left-hand doors, so one part number covers multiple cabinet layouts without changing your drilling or layout process. The flat black finish identifies this lock visually while matching flat black hardware in the job, which helps keep a consistent look across cabinetry. The 1-3/16 inch cylinder length defines how much material thickness the lock can pass through, which is critical when selecting fronts and frames to match the lock body. The CAM LOCK BLACK 8053KA-413 designation ties this unit directly to the SAP and manufacturer part C8053-C413A-Y21, helping match the correct lock to shop drawings and reorder lists. The disc tumbler design establishes the internal locking mechanism, which gives a defined keying format and supports the keying options described in the stock keying table.

Key Details That Drive Lock Selection On Jobs

• The stop washer allows the cam to turn 90 degrees, creating a defined open-and-closed position that helps align the cam with strikes or cabinet edges during layout.
• Suitability for drawers and both right-hand and left-hand doors means one lock style can be used across varied cabinet openings, simplifying planning and part stocking.
• Cams supplied for lipped or overlay construction, with a straight cam and 1-1/2 inch extension, let the cam reach farther behind the front, which is useful on overlay cabinet builds.
• Cams supplied for flush construction, with a formed cam, 1-1/8 inch extension, and 11/32 inch offset, position the cam correctly relative to the front, which helps the cam engage behind flush doors or drawer fronts.
• Key removable in both locked and unlocked positions allows the user to leave the lock in either state without the key present, which can speed up cabinet use where frequent access is needed.
• REMOVACORE versions being available means the core can be handled as a replaceable element, which helps when setting up or changing keying systems on projects that specify that option.

Cam Lock Fit, Cylinder Length, And Construction

The 1-3/16 inch cylinder length controls how the flat black cam lock fits through the front and frame, so the combined thickness of those parts cannot exceed this length in overlay applications. This matters when using a front and frame combination, because the material stack-up must allow full thread engagement on the mounting nut while still letting the cam operate freely behind the cabinet component. When the application uses a 3/4 inch front and a 3/4 inch frame in overlay construction, the Web Description specifies the NLC8053 lock and NLC7014-2C cam for that configuration, which indicates that those parts are intended to handle that particular thickness combination. The specification that the lock can be used for flush construction tells you the cylinder length and cam geometry are suited to sit within the front thickness without extra spacing.

How This Flat Black Cam Lock Works In Practice

Using The Cam Lock On Drawers And Doors

The flat black CompX National disc tumbler cam lock is specified for drawers and for right-hand or left-hand doors, so it can handle typical cabinet openings in shops, offices, or similar installations. The stop washer limiting cam rotation to 90 degrees means that once installed, the cam swings from closed to open in a quarter turn, giving a predictable handle feel for end users. When used on lipped or overlay construction, the straight cam with 1-1/2 inch extension reaches past the front, which lets it catch behind a cabinet member or strike without additional spacers. On flush construction, the formed cam with 1-1/8 inch extension and 11/32 inch offset positions the contact surface slightly back from the cylinder centerline, letting the cam clear the edge of a flush front while still engaging the mating surface.

Keying, Components, And Installation Workflow

The CompX National disc tumbler cam lock carries stock keying options defined by KA, KD, and KDMKD, with KA meaning all keyed alike to a specified key number where a master key will not work, KD meaning all keyed different where a master key will not work, and KDMKD meaning all keyed different and master keyed where a master key will operate the locks. This matters when planning access control, because it defines whether multiple cabinets share a key or respond to a master key system. Key removable in both locked and unlocked positions lets installers test operation and then remove the key in whichever position the cabinet will normally rest. The lock is supplied with two keys, a trim washer, a spur washer for wood, a mounting nut, and two cams, so the installer has the specified parts to mount the cylinder through the panel, seat it cleanly against the front, grip into wood when needed, and select the appropriate cam for lipped/overlay or flush construction. The unassembled configuration allows the installer to choose and mount the correct cam and washers based on the job conditions rather than working around a pre-assembled setup.
