Abstract
A self-closing lid is provided for a cover for a wiring device box. The cover has openings to provide access to a receptacle within the box. Each lid is formed with laterally protruding collinear gudgeons which are received in shell-like bearing members molded onto the cover. The lid and cover are each provided with a boss between which a compression coiled spring acts. The line of action of the spring is outside of the axis ine of the gugeons, causing the spring to continually urge the lid to its closed position.
