Abstract
Abstract A self protecting toggle latch assembly in which the latch handle nests in a narrow slot cut a part way through the extruded side member of the container. The slot interrupts a hole of circular cross section which is extruded throughout the length of the side member to form a hole on each side of the slot. The handle is pivotally retained in the side member by projections thereon which engage the holes formed in the side walls of the slot.
