This sealing collar and threaded ring combo bridge the gap between two 20A or 30A power cords to prevent water damage. The threaded ring is applied to the weatherproof boot on the power cord using a heat gun or similar device. The ring will then screw around the collar to keep that side of the connection watertight. Another 20A or 30A power cord with a weatherproof boot and ring will fit on the other side, keeping the connection safe from the elements.
