ABSTRACT:
A deadbolt latch assembly capable of accommodating both rectangular faceplates and circular faceplates. The latch housing assembly is provided with a semi-permanent rectangular faceplate assembly attached thereto, but which is removable with a prying tool to allow the housing to accommodate an alternative faceplate such as a circular faceplate. The housing is manufactured of a thick walled steel casing to enclose and retain not only the latch but the latch extension as well, to thereby prevent the latch extension from flexing about the latch-extension joint.
