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.

Abstract: A door retainer mechanism on a padmounted switchgear cabinet includes a pair of elongated links coupled between an access door and housing of the cabinet. The links are pivotally connected respectively to the access door and housing and also pivotally connected to one another. The links are pivotable relative to each other between folded and unfolded conditions with respect to one another as the access door is moved between closed and opened positions relative to the cabinet housing. The links are operable automatically to latch with one another in the unfolded condition upon the access door reaching the opened position after being moved by a worker from the closed position relative to the cabinet housing. The links of the door retainer mechanism, once they have reached the unfolded condition and become latched with one another, function to retain the access door in the opened position and prevent the access door from returning to the closed position.
