Abstract
Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings of novel configuration together with pivotally nestable and extensible handles that are movable relative to their housings to effect latching and unlatching movements of a resilient, expansible latch member. Locking mechanisms are mountable on the housings to selectively permit and prevent unlatching movements of the latch member. The resulting arrangement provides sturdy latch and lock assemblies that employ a small number of relatively movable parts that can be assembled and serviced with ease.
