Sliding single-point locks are essential hardware for securing sliding patio doors, balcony doors, and other residential or light-commercial sliding glass door systems. These locks use a straightforward mechanism: a single locking point extends from the lock body into a corresponding keeper on the door frame, firmly holding the door closed. Because of their focused design, sliding single-point locks are valued for their ease of use, fast installation, and effective security, making them a popular choice for door cylinder lock replacement and upgrades.

How Sliding Single-Point Locks Work

Single-point sliding door lock systems utilize a latch or bolt, operated by a turn knob or key, to secure the door at one main locking position. Many models in this collection feature a cylinder lock or thumbturn latch. The lock cylinder is either keyed, allowing for keyed-alike or keyed-different options, or operated by an interior thumb turn for quick, convenient access. This design is compatible with most residential aluminum, vinyl, and wood sliding doors, as well as certain commercial systems.

Replacement & Installation Tips
