What is meant by the term “lever latch” handles?
A. Lever latch handles have a plain back plate. They are used in conjunction with either a mortice or tubular latch which is normally 2.1/2″ or 3″ long, although longer sizes can be obtained if the handles need to be placed further in from the door edge. The latch is mortised into the edge of the door and is operated by depressing the lever on the handle. It is not supplied complete with the handles, but needs to be purchased as a separate item. The face plate on the latch is normally specified to have a matching finish to the handles. Tubular latches, the most common type of latch, offer the same function as mortice latches and are easier to fit. Mortice latches usually have stronger springs which may be more suited to heavier or unsprung commercial door handles.
