5 levers
Compared to a lock with a lower number of levers, a five-lever sash lock offers enhanced security for external doors. The extra levers make the lock more difficult to pick and provide a greater number of possible key combinations.
How a five-lever lock works
Smart Lever System: When you insert and turn the correct key, it lifts five internal levers into the exact positions needed to unlock the door.
Secure Bolt Action: Once everything is perfectly aligned, the lock’s bolt slides open or closed, letting you safely access your home.
Extra Protection: Compared to a three-lever lock, the five-lever design offers much stronger resistance against tampering or picking—giving you greater peace of mind.
Secure and protected
This sash lock requires two door handles and is designed to work with bolt-through door handles, meaning your handles are firmly attached without needing extra screws. Available in a variety of finishes and colours to match your home’s style.
Includes two keys as standard
You’ll receive two keys with your lock, so you have a spare right from the start.
