Abstract From the Canadian patent

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 a variety of types of handles that are movable relative to the housing to effect unlatching movements of spring-projected slide bolts. Locking mechanisms are mountable on the housings to selectively permit and prevent unlatching movements of the latch bolts. 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.
