CompX Timberline CB-375 Double Glass Door Lock (1/4 - 5/16 Thick) Cylinder Body Only, Non-Bore Style, Vertical Mount, Brass, CB-375

Double Glass Door Lock For Swing Showcase Doors

Double glass door lock from CompX Timberline is designed for swing style doors where locking the left and right doors simultaneously is required, so one keyed turn secures both panels on a bypassing or showcase application. This CB-375 cylinder body only configuration focuses on the core locking function, which suits installers sourcing cylinders through established keying systems. The non-bore style lock slips onto the edge of the glass door at any location, which matters when working on existing showcase doors where drilling is not desirable. A vertical mount orientation on the glass door keeps the lock body aligned with typical swing door layouts in display and cabinet installations. The brass construction provides a familiar hardware appearance that coordinates with many display and cabinet designs in woodworking environments. This lock is part of the Bypassing and Showcase Door Locks class, aligning it with common retail, display, and cabinet security layouts.

Key Working Details For Glass Door Lock Use

• The non-bore glass door lock design allows the CB-375 to slip onto the edge of the glass door at any location, which lets installers position the lock around existing hinges or frames without modifying the glass.
• Two lock throws extend 1/2 inch from the bottom and left side of the housing as you face the lock, providing positive engagement points that secure both the bottom edge and the adjacent door edge in a swing door layout.
• The fully cushioned lock body protects the glass from direct metal contact, which helps preserve the glass edge when tightening the lock in place during installation or later adjustment.
• The vertical mount on the glass door supports typical double swing door arrangements, so the lock housing aligns with the door motion for straightforward operation in a showcase or cabinet.
• The strike plate is sold separately, which allows installers to select and position the mating strike to match the casework design and the specific reveal conditions around the glass doors.

Vertical Mount And Glass Thickness Fit Details

The CB-375 double glass door lock vertically mounts on glass doors from 1/4 to 5/16 inch thick, so it covers common glass sizes used in retail showcases and cabinet displays. This thickness range gives installers predictable clamping performance on standard panels without needing alternate models for small size changes. Because the lock slips onto the edge of the glass rather than using a bored hole, it suits both new installations and retrofits where the glass is already fabricated. The non-bore, slip-on approach keeps work focused on layout and strike positioning instead of glass drilling operations. Vertical orientation of the housing further simplifies alignment with the strike plate on the cabinet or adjacent door, leading to efficient setups across multiple doors.

How The CompX Timberline CB-375 Works In Practice

Using This Lock On Swing Showcase Glass Doors

The CompX Timberline CB-375 double glass door lock is designed for swing style double glass doors where the left and right doors lock simultaneously, which fits many bypassing and showcase door layouts. By slipping onto the edge of the glass door at any location, the non-bore design lets installers place the lock at a height that matches existing shelving or framing, keeping the display clean while still controlling access. The vertical mount on 1/4 to 5/16 inch thick glass integrates into typical retail showcases and cabinet displays that use these glass sizes, so one lock model can be applied across multiple cases. Two lock throws extending 1/2 inch from the bottom and left side of the housing engage with the door edge and strike area, helping to stabilize both leaves of the double door assembly when security is needed.

Details That Support Repeatable Lock Alignment

The fully cushioned CB-375 lock body is designed to avoid glass damage, so the contact surfaces distribute clamping force along the glass edge, which matters when tightening the lock to a consistent tension across several doors. Because the lock throws extend a defined 1/2 inch from the bottom and left side of the housing, installers can measure from the housing edges to locate the strike plate position, supporting repeatable setups from one cabinet to the next. With the strike plate sold separately, the locking side can be tailored to varied cabinet framing while the lock body remains the same, helping standardize the cylinder body and layout process. The cylinder body only configuration ties into broader CompX Timberline keying plans, so shops working with these locks can align this CB-375 with existing keyed systems for organized security management.
