FAQs
WIU1T1 is designed as a single-gang, extra-duty while-in-use cover with universal mounting. It supports horizontal and vertical mounting directions and works with inserts and movable hinges in a 16:1 configuration, minimizing the need for multiple SKUs. This makes retrofits and new installations faster while ensuring a secure, code-compliant enclosure protection.
Key specs include a 6 in length, 4.1 in width, 2.64 in height, and 2.25 in depth. The cover is made of polycarbonate in a transparent gray finish and is rated for ordinary/non-hazardous locations. It supports single-gang applications with horizontal/vertical mounting, and carries NEC/CEC compliance with a NEMA 3R rating.
WIU1T1 carries a NEMA 3R rating, which provides rain and weather resistance suitable for ordinary locations. It is intended for non-hazardous environments; for harsher or hazardous locations, verify additional enclosure ratings or specialized protection. Always confirm site conditions and enclosure compatibility before outdoor deployment.
Universal mounting reduces the number of different covers needed in stock, streamlining procurement. The ability to mount horizontally or vertically, paired with inserts and movable hinges in a 16:1 configuration, enables quick adaptation to existing panel footprints and future upgrades. This translates to shorter installation times and lower total cost of ownership.
When selecting WIU1T1, ensure NEC/CEC compliance for non-hazardous locations and confirm the enclosure’s suitability for 3R-rated protection. Consider the single-gang footprint, material durability, and visibility benefits of polycarbonate. Regular inspections should verify gasket integrity, hinge operation, and the cover’s sealing performance to sustain safety and compliance over time.
