Each lock is carefully hand-assembled to ensure the inner workings dovetail together perfectly and provide a seamless operating experience and a latch that will last a lifetime.


The anti-friction latch bolt is reversible for easy installation. The grip-tight follower ensures a positive handle action whilst the anti-thrust bolt provides extra security.
