A combination door latch and deadbolt assembly includes an improved latch mechanism and deadbolt mechanism designed for use with doors having a variety of standard size backset and cross bore dimensions. The latch and deadbolt mechanisms are carried by escutcheons havings breakaway tabs at varying diametric positions to fit securely within door cross bores of different standard sizes. The latch mechanism further includes an improved mounting arrangement for left- or right-hand mounting and positive centering of lever-type door handles, together with a simplified cam-actuated latch retractor. The deadbolt mechanism includes an improved bolt linkage which provides a desired bolt throw when a relatively small door backset and/or cross bore size is used. The deadbolt mechanism further includes an improved thumb turn rotatable through ninety degrees between orientations representative of deadbolt position.
