Sliding glass door lock bright nickel from CompX Timberline is a disc tumbler ratchet lock designed for 1/4 inch or thinner sliding glass by-pass doors, so it secures typical showcase or display doors without changing the glass. The ratchet design lets the lock clamp to the glass door edge, so it creates a positive stop that resists casual pulling on the panels. Bright nickel finish gives the lock a clean, neutral appearance that matches common display and cabinet hardware, which helps jobs blend visually in retail or office environments. The disc tumbler Timberline keyway provides a keyed lock solution that integrates with other Timberline disc tumbler locks, so one key can operate both cabinet and sliding glass door locations. Non-removable lock plugs keep the core fixed in place, which supports consistent key control across installed locks.
The CompX Timberline sliding glass door lock is described as a simple tool-free installation because it does not require any boring in the glass, so the installer positions the lock on the door edge without drilling or cutting. The ratchet bar attaches to the back door and is held with a set screw, so once it is tightened the bar stays aligned with the lock body and resists sagging during use. This configuration keeps the lock from drooping down when in the locked position, which helps the keyway stay upright and easy to access at the showcase front. Because the design is for 1/4 inch or thinner glass, fitting the lock is a matter of matching the door thickness and clamping it in place along the sliding edge.
This CompX Timberline disc tumbler ratchet lock is described as the perfect lock for sliding glass by-pass doors, so it suits showcase and display applications that use overlapping glass panels. For 1/4 inch or thinner sliding glass doors, the lock grips the edge of the rear panel and uses the ratchet bar to engage the front panel when shut. Because no boring in the glass is required, it works well in finished display cases where glass cannot be removed for drilling. The bright nickel finish pairs with many commercial fixture color schemes, so the installed lock does not visually dominate the door frame. Integration with Timberline disc tumbler keyway systems allows the same key blank to operate both cabinet and sliding glass door locks, which helps consolidate keys across a run of cases or cabinets.
The disc tumbler Timberline keyway in this sliding glass door lock provides a consistent key interface across related Timberline disc tumbler locks, so keyed-alike planning is possible using the same key blank. Stocking in 5 unique key numbers gives options for separating groups of locks by key number, which supports organizing different case zones under different keys. The ratchet bar held by a set screw keeps the lock from drooping down in the locked position, so the cylinder maintains a predictable orientation that speeds daily opening and closing. Non-removable lock plugs keep the core fixed inside the housing, which avoids field disassembly and supports stable, long-term key performance. The manufacturer part number L1-330-101TA identifies this exact bright nickel sliding glass door lock configuration, so specifying or reordering the same unit across jobs stays straightforward.
