Polished Brass Victoria Mortice Door Knob Set 55mm
Victoria polished brass plain round 55mm door knob on a 57mm diameter round rose. Can be used together with a keyhole cover on doors that have a mortice door lock or with a latch for doors that are not required to lock with a key. This set is supplied complete with connecting spindle and fixing screws. The Victoria brass door knobs are sprung on one side only and should be fitted with standard spring sashlocks or tubular latches, see related items below.
Mortice knobs can be used with a latch where the door is not required to lock; a bathroom lock where you would also need to use a turn and release; or a mortice sash lock where you would also need to use a pair of escutcheons. The locks and latches are usually 2.1/2in (64mm) or 3in (75mm) wide, although longer sizes can be obtained if the knobs need to be placed further in from the door edge. Generally when using a knob rather than levers, a longer latch is required to stop your knuckles from scraping on the edge of the door frame. When using a mortice knob with a turn and release or escutcheons, these are fitted directly below the rose of the knobs and are normally of a matching size and finish. The latch or lock is fitted into the edge of the door whereas the mortice knobs are fitted to either side of the door and are connected by a spindle. When the knobs are turned, the spindle rotates and operates the latch allowing the door to open. The mortice knobs are supplied complete with the spindle and fixing screws, but not with the latch or lock, which need to be purchased as a separate item, and are normally specified to have a matching finish to the knobs.
