Yale PM320 3 Lever Mortice Sashlock in Polished Chrome - 79mm

The Yale PM320 3 Lever Mortice Sashlock provides a reliable standard level of security, making it an excellent choice for internal timber doors. Featuring a deadbolt that can be locked or unlocked from either side with a key, this sashlock ensures convenient operation while maintaining security. The 13mm anti-saw deadbolt enhances protection against forced entry.

Designed to work seamlessly with door furniture, the Yale PM320 combines functionality with aesthetic appeal. The polished chrome finish not only adds a sleek, modern look to your door but also offers durability against wear and corrosion. Mortice sashlocks, unlike deadlocks, include both a deadbolt and a latch, with the latter operated by lever handles for ease of use.

Security in mortice locks is determined by the number of levers, with the Yale PM320 offering three levers for a balanced level of protection. With a case size of 79mm x 101mm (3 inches) and a backset of 57mm, this lock is perfectly suited for UK standard door fittings. The backset measurement — from the edge of the door to the centre of the keyhole — along with the 57mm centre measurement (from the follower to the keyhole centre), ensures compatibility with most UK door setups.
