A18R184NK

Overview

The Hoffman Enclosures A18R184NK is a NEMA Type 3R drip shield enclosure constructed from mild steel. It features an unflanged design with dimensions of 18 inches in height, 18 inches in width, and 4 inches in depth. The unit utilizes a screw cover mechanism for access. The exterior finish consists of galvanized steel coated with polyester powder paint in ANSI 61 gray. The construction specifies 16-gauge material for both the body and the cover. This component is certified to UL 50 and UL 50E standards.

Feature Summary

• NEMA Type 3R rating provides protection against falling rain and sleet
• Unflanged design facilitates flush mounting applications
• Screw cover ensures secure closure without hinges
• Galvanized steel substrate with polyester powder coating offers corrosion resistance

Applications

• Outdoor wiring enclosures
• Junction box installations
• Equipment housing in wet environments

Procurement Notes

Verify that the specific project requirements align with the absence of knockouts, as this model is specified without pre-formed openings. Confirm that the 18x18x4 inch internal volume meets spatial constraints for intended components. Ensure compatibility with existing mounting infrastructure given the unflanged configuration. Check local environmental regulations regarding the polyester powder finish if specific chemical exposure is anticipated.

Selection Notes

Select this model when outdoor weather protection is required but flanged mounting is not necessary. The 16-gauge steel construction provides structural rigidity suitable for standard industrial loads. The screw cover design is appropriate for applications where frequent access is not required or where hinge durability is a concern. Verify that the ANSI 61 gray color matches facility aesthetic standards.

Part Context

This part belongs to the Hoffman NEMA Type 3R series of wall boxes. These enclosures are designed for general-purpose outdoor use. The product line emphasizes durability through galvanized steel construction and protective coatings. The A18R184NK represents a specific size variant within this broader category of drip shield enclosures.

Replacement Considerations

Direct substitutes include other NEMA 3R screw cover enclosures with identical 18x18x4 dimensions and no knockouts. Ensure replacement units maintain the 16-gauge thickness and UL 50/50E certification. Verify that alternative models offer comparable corrosion resistance through similar galvanization and powder coating processes.
