ABSTRACT The lever assembly is of two principal parts, a lever with a circular aperture to engage the shank of a door knob, and a retaining plate, for fastening thereof to the lever, having a projecting cog. The cog engages a knob catch slot in the door knob shank. Accordingly, as the lever is rotated/manipulated, it turns the door knob through the engagement of the cog with the slot, and the fastening of the plate to the lever. The assembly accommodates retrofitting thereof to doors having round door knobs.
