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.

DETAILED DESCRIPTION With the prior art drawbacks in view, it is a principal object of the present invention to provide a hook bolt lock set having a strike plate that can be adjusted for proper engagement with the hook bolt simply by inverting the plate itself.
According to the present invention, a hook bolt lock set for use on a pair of sliding doors having a pair of meeting stiles has a strike plate for being attached to one of the meeting stiles.
The strike plate 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 is 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 due to misalignment, the strike plate is inversed to let a wider one receive the hook bolt unobstructedly.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheet of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
