Charlston Art Deco Style Polished Brass Keyhole Door Knob Set
£52.44 £43.70 Pair
Charlston polished brass door knob on an Art Deco style keyhole backplate. Used on doors that have a mortice door lock operated with a key. The backplate measures 200x65mm and the knob is sprung on one side. This set is supplied complete with connecting spindle and fixing screws.
Mortice knob lock handles have a keyhole cut into the back plate. They are used in conjunction with a mortice sash lock, which is usually 2.1/2in (64mm) or 3in (75mm) wide and consists of a latch and a deadbolt. The sash lock is fitted 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 in the sash lock allowing the door to open. When the key is turned the deadbolt is operated, locking the door. The handles are supplied complete with the spindle 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.
