An adjustable latch assembly which is to be operated by an operator assembly having a rotatable spindle including a half round actuator and a pair of connection stems which are to be inserted into the adjustable latch assembly, comprising a cover including a central opening for receiving the half round actuator, having a pair of stop surfaces for limiting clockwise or counterclockwise rotation of the half round actuator and a stem receiving hole in the end portion remote from the stop surfaces, a housing for supporting the cover for displacement from one backset location to a second backset location, having a central hole selectively configured so that the cover central opening will be unobstructed at either backset location, a first stem hole aligned with the cover hole when the cover is at one backset location, a second stem hole, which with the first stem hole, will receive the operator stems when the cover is at one backset location, and a third stem hole rearwardly spaced from the second stem hole a distance corresponding to the backset difference, a latch-bolt head, a retracting assembly operable to displace the latch-bolt head including a displaceable retracting member having rearwardly extending legs for engaging the half round actuator when the cover is at one backset location, and a backset converter having rearwardly extending legs and an effective length equal to the backset difference, the housing supporting the backset converter for displacement from a retracted position so that when the cover is at one backset location, the half round actuator can be inserted into the central opening forwardly of the backset converter engaging the retracting member legs to an advanced -8- position against the retracting member so that when the cover is at a second backset position, the half round activator can be inserted into the central opening rearwardly of and engaging the backset converter legs. -9-
