A18R186NK

Overview

The Hoffman Enclosures A18R186NK is a Type 3R metallic pull box constructed from steel with a galvanized, polyester powder-coated finish in ANSI 61 gray. It measures 18 inches in height, 18 inches in width, and 6 inches in depth. The enclosure features a screw-on cover closure method and is rated NEMA 3R and IP32. It is designed for outdoor applications requiring protection from rain, sleet, and snow.

Feature Summary

• Provides environmental protection against falling rain, sleet, and snow for outdoor control applications
• Features a drip-shield design to prevent water ingress into the enclosure interior
• Constructed from durable steel with a corrosion-resistant galvanized and powder-coated finish

Applications

• Outdoor wiring junction boxes
• Protection of electrical controls exposed to weather elements
• Industrial pull box installations requiring Type 3R rating

Procurement Notes

Verify that the required NEMA 3R and IP32 ratings align with local environmental exposure conditions. Confirm that the 18x18x6 inch dimensions accommodate all internal components and wire bending space requirements. Ensure the screw-cover closure mechanism meets security and accessibility needs for the installation site.

Selection Notes

Select this model when outdoor protection from precipitation is necessary but submersion or hose-directed water resistance is not required. Compare against Type 4 enclosures if higher levels of dust or washdown protection are needed. Verify that the steel construction and gray finish are compatible with the surrounding infrastructure aesthetics and corrosion environment.

This component belongs to the Hoffman B-Style Body Enclosure series, which offers standardized sizes for industrial control applications. The Type 3R rating specifically addresses outdoor weather protection needs common in utility and manufacturing environments. It serves as a fundamental housing solution for distributing and protecting electrical connections in harsh external conditions.
