Claim 21:
22. A method of installing a rod actuated mortise latch, the method comprising:
inserting a rod into a door, wherein the rod includes a threaded portion including a nut;
aligning the threaded portion with a mortise opening formed in the door;
inserting a mortise latch having a chassis and a rod coupler into the mortise opening;
receiving the nut in a channel of the rod coupler, wherein the channel secures the nut and inhibits rotation of the nut relative to the channel;
rotating the rod to move the nut along the channel until the nut is moved into engagement with a stop of the rod coupler;
transmitting force between the rod and the rod coupler with the nut, wherein transmitting force between the rod and the rod coupler with the nut moves the stop with the nut;
moving a latch head between an engaged position and a disengaged position when the rod coupler moves along a longitudinal axis of the rod; and
moving a deadlatching slide between a deadlatching position and a free position, wherein the deadlatching slide engages a catch of the latch head in the deadlatching position when the latch head is in the engaged position.
