CompX National Disc Tumbler Cam Lock, 1-3/16" Cylinder with 90 Degree CW Rotation, Flat Black C8053-C390A-Y21
Description
CompX Disc Tumbler Cam Lock For Cabinets
CompX National disc tumbler cam lock gives a keyed locking point for drawers and cabinet doors, so casework can be secured with a compact cylinder. The 1-3/16 inch cylinder length supports applications where the front and frame thickness must stay within that dimension, which guides material choices on overlay jobs. Flat black finish provides a low-visibility look on darker casework, helping hardware blend into the project. The lock body works with right-hand or left-hand doors, so the same part number can serve multiple swing directions on a run. Stock keying options KA, KD, and KDMKD define how locks are keyed in a project, which affects how keys are issued and controlled across installations. Key removable in both locked and unlocked positions allows a keyholder to remove the key after any cycle, which affects how users manage access on site.
Key Working Details That Support Daily Use
- The 90 degree clockwise rotation created by the stop washer controls the cam travel, so door or drawer movement can be planned around a quarter-turn motion that is quick in repetitive use.
- Cams for lipped or overlay construction and for flush construction give options between a straight cam with 1-1/2 inch extension and a formed cam with 1-1/8 inch extension and 11/32 inch offset, so the same lock style can adapt to different cabinet builds.
- Key removable in both locked and unlocked positions means users can remove the key regardless of cam position, which can simplify key handling in environments where multiple operators share access.
- Stock keying choices KA, KD, and KDMKD define whether locks share keys, differ, or operate under a master key, which helps align lock selection with key control policies on a project.
Cam Lock Installation And Fit Considerations
The 1-3/16 inch cylinder length sets the maximum combined thickness of front and frame for overlay applications, so door and frame build-ups are selected to stay within that limit. The stop washer that creates 90 degree clockwise rotation also positions the cam swing, which affects where the strike surface lands on the cabinet. For overlay jobs using a 3/4 inch front and a 3/4 inch frame, the product notes state that the NLC8053 lock and NLC7014-2C cam are used, which shows this model is targeted to thinner combined overlays. Straight and formed cam options give flexibility in how the cam reaches the strike area, so installers can choose geometry that lines up with either lipped or flush constructions.
Using This CompX Cam Lock In Cabinet Work
Where This Disc Tumbler Cam Lock Fits Best
This CompX National disc tumbler cam lock is identified for drawers and for right-hand or left-hand doors, so it fits general cabinet storage where a single-point latch is acceptable. The flat black finish works visually on darker casework or fixtures where a subdued lock appearance is preferred, tying into design-driven millwork. The cam options for lipped or overlay construction and for flush construction let one lock body serve face-frame overlays, frameless cabinets, or inset panels, so shops can standardize on a single lock style across varying cabinet designs. The 1-3/16 inch cylinder supports applications where the combined material thickness at the lock bore stays within that measurement, guiding where this model is specified in a cabinet line.
Lock Details That Support Repeatable Results
The 90 degree clockwise cam rotation delivered by the stop washer standardizes how far the cam travels, so drilling patterns and strike positions can be laid out consistently across a run of cabinets. The straight cam with 1-1/2 inch extension reaches further behind the front, which helps when engaging a strike on lipped or overlay construction, while the formed cam with 1-1/8 inch extension and 11/32 inch offset shifts the contact point for flush construction, supporting tight, repeatable engagement on inset doors or drawers. Stock keying options KA, KD, and KDMKD define keying strategy: KA keeps multiple locks on the same key number, KD keeps each lock on a different number, and KDMKD layers a master key over different lock numbers, which helps align lock selection to how access is organized in a facility. Key removable in both locked and unlocked positions also simplifies standardized operating procedures, because users do not need to leave the cam in a particular position before removing the key.
