Abstract
A wiring device with a pivotable and rotatable cover wherein the cover has a seal which is movable relative to the cover. The seal includes a resilient ring or disk carried by a stiff supporting disk loosely retained in the cover. When the cover is closed and rotated to tighten the cover on the device, the seal frictionally engages the mouth of the device and the cover rotates relative to the seal, avoiding damage to the seal.
