ABSTRACT:
A door latch for passage and privacy applications provides capability for non-handed installation as well as independent bolt operating cams which may be selectively locked or may be unlocked by retraction of the bolt or by pushing the bolt inward when the door is closed. The latch also provides for removal of the bolt from the latch assembly when the faceplate is not attached. Dual backset capability is provided by means of telescopic forward housings and bolt-to-drawbar assemblies which may be placed in two indexable positions to adjust the length.
