Abstract
A dual backset latch bolt assembly includes at least one pair of cam members mounted on at least one side plate of a latch housing. The latch bolt assembly is provided with positioning holes and engaging notches so that the assembly can be used in combination with a lock having either positioning female screws or guide plates for attachment. The latch bolt assembly may be arranged such that two pairs of cam members are mounted respectively on two side plates of the housing, thereby permitting the latch assembly to cooperate with a lock having either a single rotary spindle or two rotary spindles which are respectively associated with two parts of the lock operable from the outside and inside of a door.
