Single point locks are specialized locksets that secure a window or sliding patio door at one location, typically using a latch and deadbolt housed in a mortise body. Compared to multi-point systems, these locks offer a straightforward, reliable solution for smaller windows, patio sliders, and select door models that do not require multi-point reinforcement. AmesburyTruth single point locks are engineered for durability and consistent performance, making them the trusted choice for both residential and commercial applications.

Where Single Point Locks are Used

These locks are most commonly found on sliding patio doors and certain casement or awning windows. Their single locking position is ideal for units where robust security and smooth actuation are needed,but where a multi-point system would be unnecessary or incompatible. Many classic Marvin, Caradco, and Jeldwen doors, as well as numerous aluminum and vinyl patio doors, use single point mortise locks as their primary locking hardware. If your door or window originally used an AmesburyTruth lock, replacement with genuine parts ensures proper fit and continued performance.
