Abstract

A hook bolt lock set used on the meeting stiles of a pair of sliding doors has a hook bolt lock mounted in one of the meeting stiles and having a hook bolt capable of projection toward and retraction from the other meeting stile in a direction normal to the planes in which the doors are movable. A strike plate is attached to the other meeting stile and has a central opening and a pair of bolt apertures located one on each side of and symmetrically in position with respect to the central opening, one of the bolt apertures being wider in width than the other. When the doors are fully closed and if the hook bolt fails to be received in a narrower bolt aperture, then the strike plate is turned upside down to let a wider one receive the hook bolt unobstructedly.
