A10R104HM

Overview

The Hoffman Enclosures A10R104HM is a horizontal-mount electrical enclosure constructed from steel with a galvanized, polyester powder-coated finish in ANSI 61 gray. It measures 10 inches by 10 inches by 4 inches and carries NEMA Type 3R and UL 50/50E ratings. The unit features a screw-on cover design and is engineered for direct installation on rooftops or pads without requiring vertical mounting structures.

Feature Summary

• Horizontal mounting configuration eliminates the need for vertical support structures
• Galvanized steel construction with polyester powder coating for corrosion resistance
• Screw-on cover design for secure access and protection

Applications

• Rooftop installations
• Pad-mounted applications
• Wiring junction points

Procurement Notes

Verify that the specific project requirements align with the NEMA Type 3R rating, which protects against rain and sleet but does not provide dust-tight sealing. Confirm that the horizontal orientation matches the physical layout constraints of the intended rooftop or pad site. Ensure compatibility with existing conduit entries and internal component spacing within the 10x10x4 inch dimensions.

Selection Notes

Select this model when vertical mounting space is unavailable or impractical. It serves as an alternative to standard vertical enclosures for outdoor wiring needs. Consider the galvanized steel material for environments where rust prevention is critical. Verify that the 4-inch depth accommodates all necessary internal components and wire bending radii.
