ABSTRACT:
A latch apparatus includes a live bolt actuated between an extended position and a retracted position, first and second dead bolts, and a slide. The first dead bolt is positioned vertically above the live bolt and the second dead bolt is positioned vertically below the live bolt. The first and second dead bolts have substantially the same size and shape and are spaced equidistant from the live bolt. The slide couples the first and second dead bolts to each other, wherein vertical movement of the slide simultaneously actuates the first and second dead bolts between extended and retracted positions.
