Abstract: Flush mountable latches and locks for industrial cabinets, tool carts, electrical equipment enclosures and the like utilize versatile housings together with a variety of types of handles that are movable relative to the housings to effect unlatching movements of spring-biased, pivotally mounted latch bolts, with pivotally mounted operating arms serving to drivingly interconnect the handles with the latch bolts. Lockable embodiments have locking mechanisms that prevent operating movements of the operating arms, but do not prevent pivotal movement of the latch bolts out of their latched positions, whereby even the lockable embodiments have latch bolts that can be "slammed" into latching engagement with suitably configured strike formations.
