CompX National Deadbolt Lock For Secure Drawers

CompX National deadbolt lock is a pin tumbler deadbolt lock designed for drawer security, so it provides a defined keyed locking point where a dependable lock is required on casework or cabinetry. The lock uses a pin tumbler mechanism, which provides a positive key-operated action that suits repeatable use in commercial or shop environments. It requires a 57/64 inch diameter hole for the cylinder, so the drawer or panel boring operation is straightforward and repeatable with the correct bit size. The key is required to engage the lock, so locking cannot occur accidentally without a deliberate key turn during closing or securing. The key is removable in both locked and unlocked positions, which lets installers or users remove the key after setting the preferred state, supporting different workflow habits around access control on drawers.

Deadbolt Drawer Lock Details That Save Time

• The requirement for a 57/64 inch diameter hole for the cylinder defines the boring setup, so fabricators can standardize drilling operations and avoid trial-and-error fitting during assembly.
• The key-operated engagement means the lock can only be set by turning the key, so users gain predictable locking behavior on drawers in daily use.
• The removable key in both locked and unlocked positions supports flexible key management, so supervisors or users can control when keys stay with the lock or are stored separately.
• ANSI/BHMA Grade 2 A156.11 certification ties the lock to a recognized performance standard, so specifiers can align projects with established commercial hardware criteria.
• Stock keying options KA (all keyed alike) and KD (all keyed different) define how groups of locks are keyed, so planners can match key strategy to how many drawers or stations will share access.

Drawer Lock Boring And Keying Setup

This CompX National pin tumbler deadbolt lock requires a 57/64 inch diameter hole for the cylinder, so layout and drilling on drawer fronts or panels can be based on a single defined bore size. That fixed bore diameter streamlines jig design for production shops and reduces layout time on site-built casework. The keyed alike (KA) option sets all locks in a group to the same key number, so multiple drawers can be operated with one key where shared access is needed. The keyed different (KD) option assigns various lock numbers, so individual drawers can have separate keys where separation of access is important. The lock uses a key to engage the bolt, which provides a controlled locking step during install checks and handover.

Where This Pin Tumbler Deadbolt Lock Fits Best

This CompX National pin tumbler deadbolt lock functions as a deadbolt for drawers, so it suits cabinetry or casework where a positive bolt action is preferred over simple latches. The 57/64 inch diameter cylinder bore defines its mounting interface, so any drawer front or panel that can accept that bore size can be prepared consistently across a run of cabinets. Because the lock is keyed alike or keyed different according to stock keying choices, it can be planned for installations ranging from single locked drawers to banks of drawers with shared or separated access. The lock is identified with part number C8178-101-26D and described as drawer lock, satin chrome, so specifiers can call out this exact dull chrome finish when matching other visible hardware in a project.

Why These Deadbolt Details Matter For Workflow

The requirement for a 57/64 inch diameter hole concentrates all fitting around one boring dimension, so installers can set up stops and drill guides once and repeat the operation across multiple drawer fronts without reconfiguring tools. The key being required to engage the lock means that during installation and adjustment, the installer controls exactly when the bolt is projected, which helps verify strike alignment and drawer closure without unplanned locking. The removable key in both locked and unlocked positions allows site personnel to leave a drawer unlocked for frequent access while still removing the key, which can support controlled circulation of keys in commercial or shop settings. ANSI/BHMA Grade 2 A156.11 certification references a recognized standard, so architects and builders tying projects to graded hardware can match this lock to specifications that call out that performance level.
