CompX National disc tumbler deadbolt lock gives drawers and similar applications a defined locking point using a deadbolt action, which matters when a project needs a clear locked or unlocked position using a keyed cylinder rather than a simple catch. The lock has a 1-1/2 inch height and a 1-7/16 inch length, so installers can plan layouts and clearances around that footprint when setting up drawer fronts or lock rails. This model is finished in bright brass, providing a brass appearance that can visually coordinate with brass-toned decorative hardware on cabinetry projects. The lock is identified as a drawer lock in the SAP description, aligning it with drawer-security tasks where a keyed lock is preferred over a non-locking latch. Being part of the CompX National deadbolt locks category positions it for use where a deadbolt-style lock body is needed instead of a spring latch.
This CompX National drawer lock uses a 7/8 inch diameter hole for the cylinder, so layouts on drawer faces or cabinet members can be drilled to that single dimension to accept the lock body. The product height of 1-1/2 inches and length of 1-7/16 inches help with planning space for the lock mechanism behind the drawer front, important when working around slides, dividers, or internal clearances. Stock keying options labeled KA, KD, and KDMKD define whether locks share keys, use all different keys, or use different keys with a master key, allowing projects to be designed around specific key-control patterns from the start. The bright brass finish ties the visible cylinder area to brass-look hardware suites, which can help maintain a consistent appearance across cabinet fronts in woodworking installations.
This lock is described as a drawer lock in a deadbolt locks product class, so it fits projects where a drawer needs a positive deadbolt engagement instead of a simple cam or catch. The 1-1/2 inch height and 1-7/16 inch length let it fit within typical cabinet drawer construction while still providing room for the locking mechanism behind the front. A 7/8 inch diameter cylinder hole suits drawer fronts thick enough to support that bore without weakening the face, which is common in many cabinet and casework applications. Being a CompX National disc tumbler deadbolt lock positions it for use in woodworking jobs that call for a disc tumbler key system, so shops that already work with CompX National key systems can stay within a familiar lock family on new projects. The bright brass finish supports use in installations where brass-toned decorative pulls or hinges are used, aligning the visible lock components with the rest of the hardware set.
The specified 7/8 inch cylinder hole requirement provides a clear drilling dimension, which helps reduce rework because boring tools and jigs can be set once and used across multiple drawers. The 1-1/2 inch height and 1-7/16 inch length detail the overall lock footprint, so casework designers can set drawer layouts and internal dividers to avoid interference with the deadbolt housing. The bright brass finish impacts how the lock presents on the drawer face, letting hardware planners coordinate lock cylinders with brass pulls, hinges, or other visible components for a unified look. Clear stock keying codes KA, KD, and KDMKD define how keys relate across multiple locks, letting project planners decide whether all drawers share one key, each drawer uses its own key, or a master key can operate multiple individually keyed locks. Reference to NLC2017 Series when a trim ring is required ties cosmetic trim selection to a specific series, simplifying ordering and helping keep the cylinder edge detail consistent across a bank of drawers.
The C8703-C415A-3 is a CompX National disc tumbler deadbolt lock described as a drawer lock, so it provides keyed deadbolt locking for drawer-style applications.
This drawer lock requires a 7/8 inch diameter hole for the cylinder, allowing installers to set boring equipment to a single dimension for consistent fits across multiple drawers.
The lock requires a key to engage the lock, and the key is removable in both locked and unlocked positions, which supports flexible key handling during everyday use.

Stock keying is specified as KA, KD, and KDMKD, giving options for all keyed alike, all keyed different, or all keyed different and master keyed keying patterns.
The web description notes that if a trim ring is required, the NLC2017 Series should be referenced, tying trim selection to this lock family.
