ABSTRACT:
The invention generally relates to a latch apparatus having a locking live bolt. One embodiment of the invention is a latch apparatus having a housing with opposed plates that are spaced apart and secured to each other by support arms formed from the plates. A live bolt of the apparatus is slidably mounted in the housing and horizontally actuated between an extended and a retracted position. A live bolt hub is mounted in the housing and actuates the live bolt. A slide, actuated by a rotatable cam, is mounted in the housing and moves vertically between a first position and a second position. In the first position the slide is disengaged from the live bolt, and in the second position the slide locks the live bolt in an extended position.
