A latch assembly includes a housing for inserting through an opening or breach in a door panel and secured to the panel by a retaining cage. In the preferred embodiment, the housing and the breach will have the same cross-sectional square shape. A retaining cage includes a retainer plate and a plurality of supporting legs and substantially surrounds the housing when the assembly is mounted on a door panel. At each cornering edge of the housing, a depression is formed for receiving a retainer extension formed at the end of each supporting leg. Each supporting leg also includes a support claw or tip which, in the mounted position, engages a surface of the door panel and pierces any non-conductive coating thereon so that the rotary bar handle and the other parts of the assembly may be electrically grounded. The cooperative configuration of the housing and the retaining cage permits mounting of the assembly in one of four positions. The invention is especially useful in constructing cabinets for electrical equipment where such cabinets must be electrically grounded.
