Heritage Balmoral Antique Brass Knob on Bathroom Plate

Bathroom locking handles are used with a bathroom mortice lock, which is usually 2.1/2in (64mm) or 3in (75mm) wide and consists of a latch and a deadbolt. The bathroom lock is mortised into the edge of the door whereas the handles are fitted to either side of the door and are connected by a spindle located in the back of the knobs. When the knobs are rotated, the spindle also rotates and operates the latch allowing the door to open. On the handle fitted to the inside of the door there is a button which when turned, operates the deadbolt on the bathroom mortice lock. On the handle fitted to the outside of the door there is an emergency release slot, usually operated by a coin or screwdriver, which can be used to unlock the door in an emergency. The turn button and the emergency release are connected by use of a smaller spindle, which passes through the bathroom lock. The handles are supplied complete with both spindles and fixing screws, but not with the lock, which needs to be purchased as a separate item, and is normally specified to have a matching finish to the handles.
