What is a Rim Latch or Rim Lock?

What are Rim Locks & Rim Latches?

Used since Medieval times, rim locks are among the oldest types of locking devices. Fitted to the surface of the door, these devices offer an abundance of character and are especially suited to Period properties.

While rim locks and box locks are often chosen for their stylish properties, they're also a great alternative if your door is too thick for an internal locking mechanism.

Rim Locks

Traditional rim locks contain a simple latch and deadbolt lock. They're designed to be fitted to the inwards-opening side of the door. The deadbolt can be locked and unlocked from either side of the door using a key. The keyhole is protected by an escutcheon on either side of the door, and the latch is operated by a pair of mortice/rim knobs. One door knob is fitted directly to the door with its rose intact, while the other door knob is mounted onto the rim lock with its rose removed.

Rim Latches (bathroom latch)

A rim latch consists of a latch (operated by a door knob) and a small deadbolt which is operated by a sliding draw bolt at the top of the lock, as opposed to a key. This means that the latch can only be locked from one side of the door (the side to which it has been fitted). Much like a traditional rim lock, a rim latch should be fitted to the side of the door which opens inwards. These latches are most frequently used in bathrooms or bedrooms that require privacy without the need for a keyhole and key.
