❓ Frequently Asked Questions

Q: What’s the difference between a 3-lever and 5-lever sash lock?

A: A 3-lever lock is ideal for internal doors, while a 5-lever sash lock offers higher security and is often used on external doors, especially those that are BS3621 certified.

Q: Can sash locks be used on both sides of the door?

A: Yes, they are designed to be operated by a handle and key from both sides.

Q: Do I need special handles for a sash lock?

A: You’ll need lever handles with a keyhole cut-out (on backplate or rose) to use with a sash lock. Matching escutcheons are used when handles are on rose.

Q: Are sash locks suitable for bathroom doors?
