FAQs
How do I install a 1″ mortise cylinder?
Simply insert the cylinder into the mortise lock body and secure it with the set screw once aligned. Always check cam orientation before tightening.
How does a mortise cylinder lock work?
A mortise cylinder lock operates by inserting a key into the cylinder, which rotates the plug to engage or disengage the lock mechanism inside a mortise-style lock body. The cylinder controls the locking bolt, allowing the door to be securely locked or unlocked when the correct key is used.
