CompX Timberline CB-351 Glass Door Lock Use

CompX Timberline CB-351 glass door lock is a non-bore style glass door lock designed for swing style doors, so it secures glass panels without drilling a hole through the glass. The lock slips onto the edge of a glass door at any location on the edge, which lets you position the locking point where it best suits the cabinet layout. It vertically or horizontally mounts on glass doors from 1/4 to 5/16 inch thick, covering a common range of showcase and bypassing door glass. The cylinder body only configuration centers on the locking body, which is useful when integrating with an existing keyed system. As part of the Bypassing and Showcase Door Locks class, it is suited to display and cabinet applications where visibility and controlled access matter.

Key Details That Support Glass Door Projects

• The non-bore glass door lock design slips onto the edge of the glass door, allowing installation on existing swing style doors without boring a cylinder hole through the glass panel.
• The lock is fully cushioned, so contact surfaces against the glass are protected, which helps reduce the risk of glass damage during normal locking, unlocking, and door movement.
• Horizontal and vertical mount styles lock to the side or bottom of a cabinet, providing flexibility to align the lock with existing cabinet framing or door swing direction.
• The CB-351 lock throw is 1/2 inch, giving a defined extension of the bolt toward the strike, which helps align engagement with the cabinet side or bottom.
• The bright nickel finish is one of three available finishes and offers a clean metallic look, which helps it coordinate with other bright nickel hardware in a cabinet installation.
• The product is sold in both broken and full box quantities, with a discount available for full box orders, which supports ordering for single jobs or larger production runs.

Glass Door Lock Mounting And Fit Details

This glass door lock is designed for swing style doors, so it works with doors that pivot rather than slide. The non-bore style allows the lock to slip onto the edge of glass doors from 1/4 to 5/16 inch thick, matching many standard cabinet glass panels. Horizontal mount styles lock to the side of a cabinet, while vertical mount styles lock to the bottom, giving layout options around shelves or frames. The lock throw of 1/2 inch defines how far the locking member projects toward the mating surface, which is important when positioning the strike on the cabinet side or bottom. Its bright nickel finish ties in visually with other bright nickel hardware in the same installation.

Using This Non-Bore Glass Door Lock In Cabinets

Where This Glass Door Lock Typically Mounts

This CompX Timberline lock is designed for swing style glass doors from 1/4 to 5/16 inch thick, so it typically mounts on showcase or bypassing-style cabinets that use that glass thickness. Because the non-bore style allows the lock to slip onto the edge of the glass, it can be positioned along the vertical or horizontal edge where the door meets the cabinet structure. Horizontal mount styles lock to the side of the cabinet, which suits doors hinged along one vertical edge and meeting a fixed side stile. Vertical mount styles lock to the bottom of the cabinet, which fits doors that close down toward a fixed base rail. The lock is fully cushioned where it contacts the glass, so it supports repeated opening and closing in display environments while helping protect the glass edge.

Why CB-351 Details Matter For Repeatable Results

The CB-351 designation identifies a glass door lock cylinder body only in the CompX Timberline line, which is useful when matching a specific lock body across multiple showcase doors. Its 1/2 inch lock throw provides a consistent distance for strike placement, so cabinet layouts using the same profile can repeat drilling and mortising locations on the cabinet side or bottom. The ability to vertically or horizontally mount on glass doors from 1/4 to 5/16 inch thick means one lock configuration can serve different cabinet door orientations while holding to the same glass thickness range. The bright nickel finish coordinates with bright nickel hardware in the same project, giving a unified appearance along with the functional locking role. As a Bypassing and Showcase Door Locks product, it fits applications where glass doors must remain transparent to view while being secured at the edge against a strike plate sold separately.
