This is the plate on which either a handle or mortice knob are mounted.
This is the distance from the edge of the door to the centre of either the spindle or the key hole.
This is a lock which can be fitted to any internal door which has a latch operated by the handle and a bolt operated by a turn and release mechanism opposed to a key.
When this type of lock is used with lever on rose handles the turn and release is purchased separately and should match the style and finish of the selected lever.
BATH SET OR BATHROOM FURNITURE:
These are lever on backplate handles with a built in turn and release mechanism for use with a bathroom lock.

This is a horizontal lever for operating the latch mechanism. These handles are usually spring loaded to ensure the lever returns to its horizontal position.
Lever handles may be preferred to mortice knobs where the door is often used by people passing through with their hands full. It is fairly easy to depress a lever with an elbow, whereas a mortice knob requires a free hand to operate it.
Double doors usually have a rebated edge where they come together when closed.
When fitting mortice locks or latches it is necessary to purchase a rebate kit to enable the forend/strike plates to fit correctly.
RIM LOCK OR LATCH:
This refers to locks or latches which are fitted on to the face of a door, opposed to a mortice lock or latch which is fitted into a recess cut into the door.
A set of rim lock furniture usually consists of a pair of rim knobs, a spindle, a rim lock and an escutcheon (key hole cover) for the outside face of the door.
A set of rim latch furniture is the same apart from the fact that an escutcheon wouldn't be required as there would not be a key hole.
A GUIDE TO DOOR HANDLES
There are three types of handles available
Lever on rose furniture is more contemporary, it can be used alone if only required to operate a latch.
If used on a door with a lock and a latch then an escutcheon (key hole cover) or turn and release will also be required.
Obviously care needs to be taken when selecting these additional items to ensure that the style and finish match those of selected handles.
Mortice knobs are becoming more popular, much the same as lever on rose furniture, you will also require an escutcheon or turn and release if used with a sash lock.
It is important to bear in mind when choosing mortice furniture, that it is more difficult to operate a door knob than a lever that could be operated with an elbow if your hands are full.
It is also important to use a latch or lock with a backset of at least 80mm, to ensure enough clearance from the door frame.
Lever on backplate are more traditional with three styles of lever.
Lever lock has a key hole cut out in the backplate and is used with a sash lock.
Bath sets have a turn and release mechanism built into the backplate and are used with a bathroom lock.
