Horizontal Locks

Horizontal locks have a wide, long case designed to sit behind a horizontal backplate, making them a traditional choice for period doors and knob furniture. Browse horizontal sash locks, bathroom locks, 3-lever locks and matching latches in a range of sizes and finishes.

Pair your lock with door knobs and use a rebate kit where required for double doors.

Horizontal Lock Buying Guide

What is a horizontal lock?

A horizontal lock is a lock case that is wider than it is tall, with the spindle and keyhole positioned side by side. This layout is designed for use with long horizontal backplates and knob sets.

How do I measure a horizontal lock?

Check the centres — the distance between the spindle and keyhole or cylinder — together with the backset and case size. These measurements need to match your existing backplate and door preparation.

Is there a bathroom version?

Yes. A bathroom horizontal lock uses a thumbturn and release instead of a key, providing privacy while working with a knob set. Check the lock dimensions and centres before ordering.
