TpreavesÂ… I was thinking the same thing. I have Oyaide R1 receptacles and with their iron grip, I can assure you something would snap if only the center screw was holding the outlet. The Oyaide WPC-Z receptacle cover addresses that issue in its engineering to mount the receptacle to the aluminum casework and subsequently using different screws mount the aluminum case to the outlet box. On the Oyaide WPC-Z, the center screw is only used to attach the very cool eye candy black carbon fiber faceplate that hides the mounting screws.
I think it would be simple enough to DYI drill holes in order to mount the receptacle by its end tabs.
