1. A vertical door latch assembly comprising:
a bolt having a catch portion comprising a recess formed within the bolt at a location that is spaced from a distal end face of the bolt, wherein the bolt includes a first outer surface and a second outer surface facing opposite the first outer surface, and with the distal end face extending from the first outer surface to the second outer surface;
wherein the recess is closed to the first outer surface and open to the second outer surface;
wherein the bolt is slidable relative to a bolt housing to allow the bolt to engage an aperture;
a latch having a retention feature that is non-rotatable relative to the latch and which engages the catch portion of the bolt, wherein a profile of the catch portion matches a profile of the retention feature to ensure a locking engagement between the catch portion and the retention feature to prevent the bolt from being removed from the aperture;
an electro-mechanical locking assembly for securing the latch between a locking position preventing movement of the bolt and a non-locking position allowing movement of the bolt; and
a controller in electrical communication with the electro-mechanical locking assembly and configured to direct the electro-mechanical locking assembly between the locking position and the non-locking position;
wherein the latch has a lever body with the retention feature for engaging the catch portion of the bolt, and wherein the distal end face of the bolt engages a portion of the lever body spaced from the retention feature and rotates the lever body to move to the locking position.
