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.
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.
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.
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.
The CompX National disc tumbler cam lock is intended for drawers and for right-hand or left-hand doors, so it fits common cabinet and casework openings using those configurations.
The 1-3/16 inch cylinder length sets the maximum combined front and frame thickness in overlay applications, which determines which cabinet material stack-ups will accept this lock body.
The stop washer on this cam lock limits cam rotation to 90 degrees, creating repeatable open and closed positions that align the cam with strikes or cabinet parts.
The straight cam with 1-1/2 inch extension serves lipped or overlay construction, while the formed cam with 1-1/8 inch extension and 11/32 inch offset positions engagement for flush construction.
The KA, KD, and KDMKD designations define whether locks are keyed alike, keyed different without master, or keyed different with a master key operating them, guiding access planning.
Key removable in both locked and unlocked positions lets users remove the key after setting the desired state, which supports workflows needing frequent access or dedicated locked positions.
The CompX National disc tumbler cam lock in flat black with a 1-3/16 inch cylinder and C8053-C413A-Y21 designation ties directly to CAM LOCK BLACK 8053KA-413 job specs, so it can be matched precisely to drawings. The defined 90 degree cam rotation, straight and formed cam options, and key removable in both locked and unlocked positions support predictable operation on drawers and on right-hand or left-hand doors. When the cabinet front and frame thickness and construction style match the described cylinder length and cam configurations, this lock can provide the specified keyed control on woodworking projects using these parameters.
