Sigma's weatherproof one-gang multi-use covers provide protection to outdoor horizontal receptacles and are configurable for GFCI, duplex and round devices. Their rugged, die-cast construction features a self-closing lid to prevent moisture penetration when receptacles are not in use. The cover is lockable to restrict unwanted access and compliment weatherproof one-gang boxes installed in wet, damp or dry locations. Covers include hardware, gasket and adapter plates for various configurations.
