Door latch

A latchbolt assembly having a first backset setting and a second backset setting, the latchbolt assembly comprising:

• a housing assembly comprising a first housing and a second housing movable relative to one another for adjustment of the latchbolt assembly between the first backset setting and the second backset setting;
• a latchbolt movably mounted to the housing assembly for movement between an extended position and a retracted position;
• a plunger movably mounted to the housing assembly for movement between a projected position and a depressed position;
• a dead latch link mounted to the housing assembly for movement between a dead-latch position and a release position, wherein the dead latch link in the dead-latch position prevents an externally-applied pushing force from moving the latchbolt from the extended position to the retracted position, wherein the dead latch link is configured to move from the release position to the dead-latch position in response to movement of the plunger from the projected position to the depressed position, and wherein the dead latch link comprises a first protrusion and a second protrusion;
• and
• a latch bar coupled with the latchbolt such that movement of the latch bar in a latch bar retracting direction drives the latchbolt from the extended position toward the retracted position;
• wherein, with the latchbolt assembly in the first backset setting, movement of the latch bar in the latch bar retracting direction causes the latch bar to engage the first protrusion to thereby drive the dead latch link from the dead-latch position to the release position;
• and
• wherein, with the latchbolt assembly in the second backset setting, movement of the latch bar in the latch bar retracting direction causes the latch bar to engage the second protrusion to thereby drive the dead latch link from the dead-latch position to the release position.
