Procurement Notes

Verify that the specific order matches the A4R44NK designation for a 4x4x4 inch size without knockouts. Confirm the material is galvanized steel and the finish is ANSI 61 gray. Ensure the NEMA Type 3R and IP32 ratings are required for the intended outdoor application. Check that the screw-cover mechanism is suitable for the installation environment.

Selection Notes

Select this model when a compact, weather-resistant enclosure is needed for outdoor use. The Type 3R rating ensures protection against falling rain and sleet. The absence of knockouts requires field drilling if cable entries are necessary. The steel construction offers durability, while the slip-on cover allows for easy access to internal components.

Part Context

This component belongs to the Hoffman A4R series of screw-cover enclosures. These units are designed for general-purpose industrial applications requiring basic weather protection. The A4R series typically features a simple, robust design with a focus on cost-effective solutions for protecting electrical hardware from environmental elements.

Replacement Considerations

Direct substitutes must match the 4x4x4 dimensions, Type 3R rating, and screw-cover style. Verify compatibility with existing mounting configurations. Ensure replacement units maintain the same galvanized steel construction and ANSI 61 color coding for consistency.
