Abstract
The metal door of metal-clad or metal-enclosed switchgear has a rectangular access opening. The access opening is closed by a molded snap-in cover assembly which includes an integral frame which contains a peripheral flange. A raised annular bead is spaced from the flange and defines, with the flange, an annular channel to permit the flange to snap into the exposed edges of the opening in the metal door. The frame has an integrally hinged cover member which can be closed over the frame to close the access opening.
