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.

A wiring device comprising a housing with an open, generally circular mouth, and a cover assembly therefor, the cover assembly including a cover and a hinge arm pivotally attached to an exterior portion of the housing and to the cover so that the cover is rotatable relative to the arm and pivotable between open and closed positions with respect to the mouth of the housing, the improvement comprising: a generally circular and relatively thin, stiff disk; means on the inner surface of said cover for receiving peripheral portions of said disk to loosely retain said disk in generally parallel relationship with said cover with one major surface of said disk facing said cover and the other major surface thereof exposed when the cover is pivoted to the open position; and an elastomeric generally circular body adhered to said exposed major surface, said body being positioned and dimensioned to engage the mouth of said housing when the cover is pivoted to its closed position so that, when said cover is closed and rotated, said elastomeric body can frictionally engage said mouth and remain substantially in position while said cover rotates relative thereto.
