Abstract
A U-shaped hinge element used to pivotally mount a door to a cover dead front of an enclosure for circuit breaker handles of a load center. The hinge element has spaced-apart wall members, and is characterized by having a projection formed out of the surface of a first wall member which positively engages a back surface of the cover dead front to partially retain the one wall member when the hinge element is initially inserted into the cover dead front and by having laterally opposed, bendable tab means formed out of the surface of a second wall member which are manually bent after the hinge element is inserted into the dead front cover. Converging slots are formed in the second wall member to form the bendable tab means, and the hinge element is made of stainless steel.
