CompX National Pin Tumbler Deadbolt Lock, Surface Mount, Keyed Alike with 103Bright Nickel Finish - C8173-103-26D

CompX Deadbolt Lock For Cabinet Doors

CompX National pin tumbler deadbolt lock gives cabinet doors a key-controlled locking point, so doors stay secured until intentionally opened. This cabinet door deadbolt lock surface mount design sits on the door surface, which keeps prep to a simple hole for the cylinder. The lock is BHMA Certified Grade 2 with lock type designation E07122, so its performance level is defined for typical cabinet applications. A 7/8 inch cylinder length reaches through standard cabinet door thicknesses, giving the cam solid engagement with the door edge. The cylinder uses a pin tumbler mechanism, which supports controlled keying and consistent operation over its service life. Key removal in both locked and unlocked positions lets installers remove the key after locking or after opening, which helps match different workflow preferences on site.

Deadbolt Lock Details That Support Daily Use

• The right and left hand cabinet door lock function means one lock model works on either handing, which standardizes parts across different cabinet runs and simplifies ordering.
• Surface mounted construction keeps the hardware on the door face, so mounting focuses on layout and cylinder drilling rather than complex mortising in tight cabinet spaces.
• Keyed alike 103 setup lets multiple locks operate from the same key code, which reduces key count when several cabinet doors need the same controlled access pattern.
• The Bright Nickel Finish provides a clean metal look on the door exterior, so visible hardware coordinates with other bright nickel components in the same installation.
• Advantage Plus feature is built into this lock, so the specified functionality is consistent with the CompX National Advantage Plus line across similar locking points.

Surface Mount Cabinet Lock Installation Focus

The surface mounted design of this CompX National pin tumbler deadbolt lock lets installers fasten the case directly to the cabinet door, so the primary operation step is drilling the cylinder hole instead of cutting pockets. It requires a 57/64 inch diameter hole for the cylinder, which defines the drilling operation and helps avoid oversized bores that could affect seating. The 7/8 inch cylinder length passes through the door and engages the lock body, so the deadbolt throw lines up properly when the hole is drilled to the stated dimension. For R.H. or L.H. doors, the same lock model works on either handing, which means layout can be mirrored without changing the product. The BHMA Certified Grade 2 designation anchors performance expectations for typical cabinet door locking duty.

Using This Cabinet Deadbolt In Real Jobs

Where This Surface Mounted Lock Fits Best

This right and left hand cabinet door lock serves R.H. or L.H. doors, so it suits mixed-hand runs such as paired cabinet banks or opposing casework. The surface mounted format keeps the case on the door face, which works well on cabinet door constructions where interior clearances are tighter or where mortising space is limited. A 57/64 inch diameter cylinder hole defines the drill work across the job, so installers can set up jigs around that dimension for repeatable boring. The 7/8 inch cylinder length is matched to that bore, so the face cylinder and internal mechanism align consistently across varying doors when drilled to spec.

Why Keying And Certification Matter On Site

The keyed alike 103 configuration lets multiple C8173-103-26D deadbolt locks share a single key code, so banks of cabinet doors can be managed with one key for daily access. This lock will key together with all other pin tumbler locks using the D4291 key blank, which supports building keying systems around a common blank across matching hardware. Master keying to GM1 is available, so keyed alike groups can still be organized under a master level in larger key systems. Key removable in both locked and unlocked positions means the key can be withdrawn after securing or after opening, which supports job sites where users prefer to keep keys separate from the lock. BHMA Certified Grade 2 status, with lock type designation E07122, identifies the lock performance classification, which helps specifiers align this unit with expected cabinet duty cycles.
