Heritage Brass Lock Mortice Knobs on Plate

Door Knobs on Lock Plates with Keyhole

Heritage Brass lock mortice knobs on plate (listed by M.Marcus as Lever Lock) have a standard keyhole below the knob for use with a mortice sashlock. They let you lock a door with a traditional key while keeping the look of a period door knob.

How it works

A keyhole below the knob lets you lock the door with a lever key via a mortice sashlock. M.Marcus lists these as Lever Lock plates.
