The IPEX fswpblank1g is a 1-gang weatherproof blank cover designed for use with FS-style conduit boxes. Made from gray PVC, this cover seals unused openings on FS boxes, preventing moisture, dust, and debris from entering the enclosure. It is a standard cover plate used in conduit wiring systems where no device is mounted in that gang position. Electricians install this cover to maintain a weatherproof rating on exterior or wet-location FS box installations. The PVC construction resists corrosion and UV degradation, making it suitable for outdoor and damp-location applications.
This blank cover is used in residential, commercial, and light industrial electrical installations wherever FS conduit boxes are mounted in exposed or weatherproof locations. Typical applications include exterior walls, covered walkways, mechanical rooms, and other areas subject to moisture exposure. It is installed when a gang position in a multi-gang or single-gang FS box does not require a device but must remain sealed to preserve the weatherproof integrity of the enclosure.
Designed as an OEM-style replacement or new-installation blank cover for standard 1-gang FS-style conduit boxes used in weatherproof electrical wiring systems.
Installation is performed by a licensed electrician in accordance with applicable NEC requirements for wet or damp locations. De-energize the circuit and verify power is off before handling any FS box hardware. Secure the cover to the FS box using the appropriate screws for the box, and verify the gasket seal is properly seated to maintain the weatherproof rating. Do not overtighten fasteners, as PVC covers can crack under excessive torque.
