The Hoffman Enclosures Inc. A6R66GV is a NEMA Type 3R steel enclosure designed for indoor and outdoor applications. It features a galvanized finish and measures 6.00 inches in height, width, and depth. The unit utilizes a screw-on solid cover mechanism for secure closure. It is rated for wall mounting and includes embossed mounting provisions. The component holds UL 50/50E, cULus, and CSA C22.2 approvals, ensuring compliance with standard electrical safety regulations for junction or wiring box usage.
Verify the specific dimensional requirements match the 6x6x6 inch specification before procurement. Confirm that the galvanized finish meets environmental exposure standards for the intended site. Ensure the screw-cover design aligns with maintenance access protocols. Check for required certifications such as UL 50/50E or CSA C22.2 depending on regional regulatory needs. Validate wall-mounting capabilities against the structural load of internal components.
Select this model when a compact, weather-resistant enclosure is required for small-scale electrical distributions. The Type 3R rating makes it appropriate for exterior walls exposed to precipitation. Consider the galvanized material for cost-effective durability in non-corrosive industrial settings. The square footprint allows for efficient space utilization in tight mounting areas. Verify that the internal volume accommodates all necessary wiring and terminal blocks without overcrowding.
This component belongs to the Hoffman NEMA Type 3R screw cover box series. These enclosures are engineered for general-purpose electrical protection. The product line emphasizes robust steel construction with standardized mounting patterns. It serves as a fundamental building block for electrical infrastructure projects requiring basic environmental sealing.
Direct substitutes include other 6x6x6 inch Type 3R galvanized steel boxes from compatible manufacturers. Ensure replacement units maintain identical external dimensions and mounting hole configurations. Verify that alternative covers utilize the same screw-fastening mechanism for compatibility with existing hardware.
