Abstract
A dual backset latch assembly includes a housing, a latch, a casing, a transmission member, an auxiliary plate, and a retractor. The retractor and the auxiliary plate are jointly movable for selective engagement with one of first and second mounting positions in a slot of the casing corresponding to shorter and longer backset lengths. When the retractor is in the first mounting position, a first mounting hole and a second mounting hole of the casing are respectively aligned with a first through-hole and a second through-hole of the auxiliary plate and respectively extended through by two mounting posts. When the retractor is in the second mounting position, a third mounting hole of the casing is aligned with the first through-hole of the auxiliary plate and extended through by one of the mounting posts, with the other mounting post extending through the second through-hole of the auxiliary plate.
