CompX National Disc Tumbler Deadbolt Lock, 1-1/2" Height with 1-7/16" Length, Bright Nickel - C8703-MKKD-14A

CompX Disc Tumbler Deadbolt Lock For Drawers

CompX National disc tumbler deadbolt lock gives you a compact drawer locking point using a deadbolt design that secures the drawer front, which matters when you need positive locking without relying on the slide hardware. The 1-1/2 inch height body keeps the lock profile small, so it fits tight drawer layouts where space around the front panel is limited. The 1-7/16 inch length provides a predictable reach for the bolt, which helps when you are aligning the strike or cabinet frame for consistent engagement. The bright nickel finish presents a clean, uniform look at the cylinder face, which suits visible drawer fronts in finished cabinetry. As a drawer lock in the deadbolt category, it suits applications where the priority is a firm mechanical stop at the locked position rather than a spring latch feel.

Key Details That Support Drawer Lock Selection

• The cylinder requires a 7/8 inch diameter hole, which defines the boring size in the drawer front and helps streamline layout when you are matching other locks drilled to the same standard.
• The key is required to engage the lock and operates the deadbolt, which means only keyed rotation drives the mechanism, reducing casual manipulation at the drawer front.
• The key is removable in both locked and unlocked positions, which lets you leave the drawer either secured or open while keeping keys with supervisors or tool managers for controlled access.
• Stock keying is offered as KA, KD, and KDMKD, which lets you match different security schemes in one project, such as groups of drawers keyed together or individually with or without master access.
• Other key changes are available from National Lock via special order, which supports projects that call for unique key series, simplifying key control across larger facilities.

Drawer Lock Mounting And Cylinder Hole Setup

This CompX National drawer lock uses a 7/8 inch diameter cylinder hole, so boring operations can be standardized around that single measurement for repeat installations across multiple drawer fronts. The 1-1/2 inch height and 1-7/16 inch length define the lock footprint, which helps when you are laying out clearances behind the drawer front so the body does not clash with side partitions or internal dividers. The deadbolt format focuses the working movement at the bolt throw, so you can align the receiving edge or strike on the cabinet carcass to take full advantage of the bolt travel. When planning retrofits, the combination of cylinder size and body dimensions provides clear reference points for adapting an existing drawer front to this specific model.

How This CompX Drawer Lock Works In Use

Drawer Applications Suited To This Deadbolt Lock

As a deadbolt lock in the CompX National line, this unit is aimed at drawer applications where a firm locked position is required instead of light-duty latching. The 1-1/2 inch height body supports mounting on standard drawer fronts without dominating the interior space, which helps when storage inside the drawer is dense. With a 1-7/16 inch length, the deadbolt can project to engage cabinet framing or a strike plate, giving a clear mechanical stop that resists casual pulling on the drawer front. The bright nickel finish on the exposed cylinder presents a consistent appearance across banks of drawers, aligning with hardware selections that favor nickel tones. Because the same 7/8 inch cylinder bore is used each time, large runs of cabinetry maintain a unified drilling pattern, which is valuable in shops setting up jigs for repeated production work.

Keying Options That Shape Security And Workflow

The lock requires a key to engage the mechanism, so locking and unlocking always happen through keyed rotation, which provides a defined control point for access. The key remains removable in both locked and unlocked positions, so drawers can be left open during active work while keys are stored separately, helping maintain control over when the deadbolt is actually put into service. Stock keying options include KA, KD, and KDMKD, and each pattern changes how access is managed across multiple locks. In a KA arrangement, all units share the same key number, simplifying use where a single key needs to open a group of drawers on a bench line. KD setups use all keyed different locks, giving each drawer a distinct key number that limits cross-access between stations or users. The KDMKD option combines individually keyed locks with a master key function, which supports environments where a central manager or foreman must have override access while day-to-day users operate only their assigned drawers. National Lock also provides other key changes by special order, which extends these patterns into larger or more complex key systems while staying within the same lock family.
