CompX National Pin Tumbler Deadbolt Lock, 57/64" Bore Diameter, Keyed Alike with Dull Chrome - C8178-103-26D

CompX National Deadbolt Lock For Drawers

CompX National pin tumbler deadbolt lock provides keyed security for drawers using a cylinder that fits a 57/64 inch diameter bore. This deadbolt style mechanism secures the drawer with a positive bolt action, which matters when a job calls for a simple keyed lock rather than a latch. The lock uses a pin tumbler cylinder, so the key operates with a familiar feel for installers working across multiple commercial and shop projects. The stock keying option KA means all locks in that keyed alike group operate from the same key number, which helps when one key is preferred across a bank of drawers. The dull chrome, also described as satin chrome, finish presents a neutral metal look that aligns with common cabinet hardware finishes in shops and workrooms.

Keyed Drawer Lock Details That Help On Site

• The required 57/64 inch diameter hole for the cylinder gives a clear boring size, so installers can set up boring equipment or bits to that specific dimension for repeatable drawer fronts.
• The deadbolt lock being ANSI/BHMA certified Grade 2 A156.11 ties performance to a recognized standard, which matters on projects that reference construction hardware grades in specifications.
• The key being required to engage the lock means the cylinder is operated only by the proper key, supporting typical controlled-access drawer layouts in shops or offices.
• The key being removable in both locked and unlocked positions lets users take the key away after locking or leave the drawer unlocked while keeping the key separate, which supports different security routines.
• The keyed alike KA option using a specified key number lets multiple locks share that key code, simplifying key sets when several drawers use the same locking pattern.

Drawer Lock Boring And Keying Use In Practice

This CompX National pin tumbler deadbolt lock centers on the 57/64 inch bore requirement, which gives a precise drilling target for drawer fronts and panels. Knowing that bore size ahead of time allows layouts for consistent centerlines across a run of casework. Because the key is removable in both locked and unlocked positions, the user can leave the drawer open for regular access or secure it and remove the key according to how the space is managed. The ANSI/BHMA Grade 2 A156.11 certification positions this deadbolt lock within a defined performance range, which can align with hardware schedules that call out grade levels. The keyed alike KA stock keying noted for the series supports lock groups where one key number is preferred.

Where This Drawer Deadbolt Fits Best

Using The 57/64 Inch Bore Diameter In Drawers

The specified 57/64 inch bore diameter for the cylinder sets the basic machining requirement for this drawer lock. When drawer fronts are drilled to that dimension, the CompX National pin tumbler deadbolt lock seats correctly, which helps the bolt project and retract as intended. This bore size gives a single reference for both jig setup and field drilling, so even varied drawer materials can be prepared to the same opening. Because the lock is identified as a drawer lock in satin, or dull chrome, it aligns with installations where a metal cylinder face is visible at the drawer front. That visible round face works in utility casework, shop furniture, and similar drawer runs where keyed control is needed.

Why Keyed Alike And Grade 2 Matter On Jobs

The stock keying information stating KA for keyed alike to a specified key number gives project planners a way to group locks under a single key. When multiple drawers use locks with the same KA designation and key number, crews and end users handle fewer keys while still keeping locked storage. The note that all locks are ANSI/BHMA certified Grade 2 A156.11 ties this deadbolt lock to a published hardware grade, which matters on commercial or institutional work where hardware schedules call for defined levels of operation and durability. The detail that the key is required to engage the lock, and can be removed whether the lock is in the locked or unlocked position, supports different control patterns, from issuing keys only to select users to holding keys centrally while drawers remain unlocked during normal hours.
