Abstract
In a weatherproof cover for an electrical receptacle, a plurality of lids are rotatably mounted in a generally rectangular base plate having three surrounding walls. A butterfly shaped biasing member is disposed between the lids and the base plate and applies a force to the lids to hold them in close proximity to the base plate in order to form a weatherproof seal. The lids cover receptacle access apertures which extend through the base plate and a stiffening plate disposed behind the base plate.
