Duplex Cover, FS Type, 1-Gang, Duplex, Vertical, Non-Metallic, Gray

Carlon non-metallic device boxes, while-in-use covers, and accessories deliver corrosion-resistant, high-capacity solutions that contractors and procurement teams can rely on. Molded from rugged non-metallic materials and finished in distinctive blue for quick identification, these single- and multi-gang boxes provide generous wiring volume, selective ENT and conduit openings, and integral mounting features for fast, secure installations. Non-metallic while-in-use covers are available in multiple depths and configurations, with gasketed seals and adapter plates to accept duplex, single, GFCI, or switch devices while maintaining weatherproof performance. A complete range of compatible accessories — closure plugs, extenders, mounting plates, pressure-sealing sleeves, and inspection covers — simplifies ordering, speeds installation, and reduces field callbacks. Designed for wet locations, corrosive environments, and direct-burial or retrofit projects, Carlon non-metallic systems deliver durable, code-conscious protection and long-term reliability.
