CompX National Pin Tumbler Deadbolt Lock, 57/64" Bore Diameter, Keyed Alike with Dull Chrome - C8178-107-26D

CompX National Pin Tumbler Deadbolt Lock For Drawers

CompX National pin tumbler deadbolt lock is a drawer lock designed for applications that use a 57/64 inch diameter bore. This required bore diameter sets the drilling layout so the cylinder seats properly and the deadbolt action works smoothly in service. The lock uses a pin tumbler mechanism, so the key engages a familiar key system that supports secure operation in typical cabinet and drawer installations. The product is described as a drawer lock with a satin chrome appearance, giving the face of the lock a dull chrome look that matches other dull chrome hardware in the same project. The cylinder requires a key to engage the lock, so the drawer stays in the chosen locked or unlocked state until the correct key is used. The key is removable in both locked and unlocked positions, which lets the installer or user remove the key after setting the position without leaving it hanging in the lock.

Deadbolt Lock Details That Support Daily Use

• The required 57/64 inch diameter hole for the cylinder gives installers a clear bore size, which helps lay out drilling operations accurately so the cylinder body fits the panel without excess play.
• The lock is ANSI/BHMA certified Grade 2 A156.11, which identifies a recognized performance grade so specifiers can align this lock with jobs that call for Grade 2 deadbolt hardware.
• The key is required to engage the lock and is removable in both locked and unlocked positions, which allows users to set the drawer either locked or open and then remove the key for separate key management.
• The product is identified as a drawer lock with satin chrome, also described as dull chrome, so hardware planners can coordinate visible lock faces with other dull chrome components in cabinets or fixtures.
• Stock keying options described as KA or KD define whether locks are keyed alike or keyed different, which lets projects standardize on one key pattern or use multiple key patterns across drawers.

Drawer Deadbolt Lock Mounting And Keying Use

This deadbolt lock requires a 57/64 inch diameter bore, so drill operations focus on that single dimension to prepare the panel for the cylinder body. Because the cylinder depends on that bore size, installers can work from that measurement when setting up jigs or drilling templates for repeated cabinet or drawer fronts. The keying information uses KA to indicate all keyed alike to a specified key number and KD to indicate all keyed different, so project planners can select a keying pattern that matches the security layout of a bank of drawers or multiple fixtures. The key being removable in both locked and unlocked positions means the user can lock, unlock, or change drawer status and then handle key storage separately from the drawer front.

Where This Drawer Deadbolt Lock Fits Best

Using The Satin Chrome Drawer Lock In Cabinets

This drawer lock, described as satin chrome and dull chrome, presents a subdued metal appearance at the front of the drawer, which helps it coordinate with other dull chrome finishes in cabinet, casework, or fixture projects. The deadbolt design is specified for drawers, so it integrates into drawer fronts where a 57/64 inch bore can be drilled to accept the cylinder. Because the key is required to engage the lock, this configuration serves drawers that need a defined locked or unlocked condition controlled by the correct key. The keying options KA and KD provide flexibility for different drawer banks, so one area can share a common key pattern while another area can use varied key numbers.

Why Keying, Bore Size, And Grade Matter

The 57/64 inch bore requirement sets a consistent drilling standard, which is useful for jig-based production where multiple drawer fronts use the same deadbolt layout. This repeatability helps keep the cylinder aligned in relation to the drawer edge and strike location. The ANSI/BHMA Grade 2 A156.11 certification assigns a specific performance grade to the lock, which assists specifiers when matching this deadbolt to job requirements that name Grade 2 for deadbolt hardware. Stock keying marked as KA, keyed alike to a specified key number, simplifies key management for installations where one key needs to operate a group of locks. Stock keying marked as KD, keyed different with various lock numbers, supports layouts where separate keys are desired for different drawers. The key being removable in both locked and unlocked positions allows the drawer to stay in its chosen state without a key left in the cylinder, which supports cleaner drawer fronts and centralized key storage.
