Abstract
A latchbolt has an adjustable backset made possible by the selection of one of a plurality of insets to interfit with the latchbolt actuator stub. The insets provide a selection in the distance between the actuator work shoulders and the end of the stub. A sleeve telescopes over the latchbolt tailpiece to hold the inset in position.
