CompX National disc tumbler deadbolt lock is a deadbolt-style lock designed for drawers where a positive bolt throw is needed. The lock has a 1-1/2 inch height and 1-7/16 inch length, so it suits drawer fronts that can accommodate this compact body while still leaving room for surrounding hardware. The cylinder uses a disc tumbler mechanism, which provides key-controlled locking that suits cabinets and woodworking projects needing keyed security. The cylinder requires a 7/8 inch diameter hole, giving installers a clear boring size that speeds layout when drilling drawer fronts or lock rails. The bright nickel finish provides a clean, metal look that matches other bright nickel hardware, helping maintain a consistent appearance across a run of casework or built-ins.
The lock requires a 7/8 inch diameter hole for the cylinder, so installers can plan tooling and jigs around that single dimension when laying out drawer fronts. The 1-1/2 inch height and 1-7/16 inch length give a compact footprint behind the front, which helps the body clear side panels or internal dividers in many drawer configurations. The bright nickel finish on the exposed cylinder face allows the lock to blend visually with other bright nickel cabinet fittings, which is useful when aligning with existing knobs, pulls, or hinges. When a trim ring is desired around the cylinder, the product is referenced with the note that if a trim ring is required, see NLC2017 Series, so planners can coordinate the front appearance.
This drawer lock is identified as a deadbolt lock in the Locks and Latches - Deadbolt Locks category, so it is suited to applications where a solid bolt engagement into the cabinet or drawer frame is preferred over a simple latch. The 1-1/2 inch height allows the body to sit behind the drawer front while the cylinder passes through the 7/8 inch diameter hole, giving a straightforward path from the key face to the bolt mechanism. With the key removable in both locked and unlocked positions, this deadbolt lock works well on drawers that are regularly accessed, because users can lock the drawer when needed and then remove the key without leaving hardware protruding from the front. The bright nickel finish described in the SAP as drawer lock bright nickel helps this unit sit visually alongside other bright nickel components in the same casework run.
The manufacturer part number C8703-KD-14A identifies this specific CompX National disc tumbler deadbolt lock, which helps shops and specifiers call out the same lock consistently on drawings or repeat orders. Stock keying is specified using KA, KD, and KDMKD codes, and the description states that KA means all keyed alike to the key number specified with no master key function, which matters when a group of drawers must open with one key but stay isolated from any master system. KD is defined as all keyed different with various lock numbers and no master key function, which suits situations where each drawer or cabinet needs its own key pattern without any higher-level override. KDMKD is defined as all keyed different and master keyed, with a master key that will work on these locks, which is useful in managed environments where individual users have their own keys while a supervisor key can operate every lock. The web description notes that other key changes are available from National Lock via special order, giving planners additional flexibility when laying out key systems for casework projects.
