ABSTRACT:
The weatherproof box cover has a pair of lids which are biased towards each other so as to be self-closing. Each lid has a gear-like portion which meshes on the other so as to synchronize movement of the lids to each other. In addition, each lid has a recess along the outer edge in which a resilient sealing strip seats. When closed over a cord of an electrical appliance, the sealing strips conform to the shape of the cord while the lids are brought into seal-tight relationship. In this way, a water spray and the like is prevented from entering into the cover from any direction.
