ABSTRACT:
A cover plate is provided for an access opening in a plate structure that forms part of a housing. The cover plate has a rod at one end thereof that has opposite ends bent toward the plate structure and engaging the internal surface of the plate structure. The plate structure also has lips thereon that engage the internal surface of the plate cover and limit movement of the plate structure to a position in which its edges are co-extensive with the edges of the opening. A further means is provided between the plate structure having the opening and the cover plate which draws the cover plate into engagement with the stops or lips while, at the same time, distorting or stressing the rod as the rod end of the cover is forced into the closed position. By placing such stress on the rod, the entire plate cover is held firmly against the lips and is prevented from rattling or becoming loose.
