Copper-free aluminum construction delivers corrosion resistance and lighter weight, reducing installation fatigue and shipping costs while maintaining strength in rugged environments. This material choice directly improves long-term reliability in busy industrial facilities and simplifies compliance with environmental exposure. The 3-1/8 inch inside depth and 1 inch tap size provide a compact yet versatile enclosure that fits tight control panels and reduces the need for field modification, accelerating project timelines. With four hubs and three plugs, GRF339 offers flexible routing for power and control wiring, enabling faster panel revisions and easier future upgrades without replacing the enclosure. The blank back boss supports customization for future I/O expansion, while surface mounting and built-in lugs streamline installation, minimizing labor and reducing total installed cost. NEC/CEC compliance and UL certification further mitigate regulatory risk across US and Canada projects.

FAQs
GRF339 is designed for surface mounting in non-hazardous industrial locations. It provides a 6.13 in length, 4.56 in height, and 3.13 in width with a 3-1/8 in inside depth and a 1 in tap size. With four hubs and three plugs, plan wiring runs to minimize bending radii and ensure compatible conduit fittings. The copper-free aluminum construction helps manage weight and corrosion, while the blank back boss offers room for future expansion.
GRF339 carries NEC/CEC compliance and UL certification for metallic conduit outlet boxes, with an area classification suitable for Ordinary/Non-Hazardous Locations. These certifications simplify regulatory approvals in US and Canada, reduce project risk, and enable faster commissioning. The catalog and UL documentation confirm the enclosure’s suitability for standard industrial electrical installations.
GRF339 is classified for Ordinary/Non-Hazardous Locations, indicating suitability for indoor or sheltered environments typical of factory floors and equipment rooms. For outdoor or hazardous-area applications, verify applicable IP/IEC ratings and additional enclosure protection or select a GRF variant designed for those conditions. Always align with NEC/CEC requirements and UL listings for the specific location.
Copper-free aluminum provides lightweight strength and excellent corrosion resistance, reducing maintenance needs in aggressive environments. For GRF339, this material improves ease of handling and installation while delivering long-term durability in hydraulic, chemical, or dusty plants. Its compatibility with standard surface mounting practices and lugs accelerates retrofits and reduces total installation time.
Using GRF339 can reduce field labor due to its surface-mount design and ready-to-use lugs, which shortens commissioning time. The robust aluminum construction lowers corrosion-related maintenance, while NEC/CEC and UL certifications mitigate regulatory risk and potential rework. Combined, these factors translate into lower total cost of ownership and quicker project payoff in control panel builds.
