The CRL Polished Stainless Dust Proof Keeper is designed for floor-mounted glass door locking systems that use a plunger-style latch bolt. This keeper accepts a 5/8 inch (16 mm) diameter plunger bolt, making it compatible with a wide range of architectural and commercial glass door hardware applications.
Manufactured from solid stainless steel, the keeper provides dependable structural support while maintaining a clean, modern appearance. The polished stainless finish complements contemporary glass door installations and integrates smoothly with surrounding hardware without introducing visual clutter.
This dustproof keeper is intended for use with AMR205 Patch Locks, 777S, 777SL, and 777EC door rail floor locks, as well as locking ladder pulls and other lock systems that rely on a plunger-type latch mechanism. Its design supports consistent latch engagement by maintaining proper alignment between the door-mounted plunger and the floor-mounted keeper.
Installation requires drilling a 1 inch (25 mm) diameter hole into the floor to a depth of 2 inches (51 mm). These dimensions allow the keeper to sit securely within the floor while providing sufficient clearance for smooth plunger movement. Proper installation helps ensure reliable locking performance during repeated door operation.
The dustproof construction helps limit debris accumulation inside the floor bore. By reducing the entry of dirt and particles, the keeper supports smoother latch operation and helps maintain consistent performance over time. This makes it suitable for commercial, retail, and architectural glass door environments where durability and functionality are essential.
Designed with a modern style and precise dimensional compatibility, this polished stainless dust proof keeper serves as a dependable component within glass door locking assemblies that require accurate plunger engagement and floor-mounted support.
