Levers on rose handles 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 handles need to be placed further in from the door edge. When using the levers with a turn and release or escutcheons, these are fitted directly below the rose of the levers and are normally of a matching size and finish. The latch or 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 levers. When the levers are pressed, the spindle rotates and operates the latch allowing the door to open. The levers 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 levers.
