A latch bar which is slidably mounted between the plates. A pair of fasteners extending from the latch bar, wherein the fasteners include a first and second threaded region, separated by a non-threaded region. The threaded regions of the fasteners threadedly engage the threaded openings of the one mounting plate, while the non-threaded region bypasses the opening.
