A4412RT

Overview

The Hoffman A4412RT is a slip-on cover wiring trough constructed from 16-gauge steel with an ANSI 61 gray polyester powder-coated finish. It measures 4 inches in width, 4 inches in height, and 12 inches in length. The unit features a screw-on cover closure and includes embossed mounting holes for installation. Designed to NEMA Type 3R standards, it provides protection against rain, sleet, snow, and humidity. The assembly weighs approximately 5.8 pounds.

Feature Summary

• Provides environmental protection for wire and cable distribution in outdoor settings
• Features a slip-on removable cover with screw-on closure for secure access
• Constructed with drip shield top and seam-free sides, front, and back

Applications

• Protecting wire and cable distribution in outdoor applications
• Safeguarding junctions and terminations exposed to weather elements
• Indoor/outdoor installations requiring NEMA Type 3R compliance

Procurement Notes

Verify the specific material gauge (16 gauge) and finish type (ANSI 61 gray polyester powder coat) against project specifications. Confirm that the NEMA Type 3R rating aligns with the required environmental exposure levels for rain, sleet, and snow. Ensure the physical dimensions (4x4x12 inches) fit the designated routing space. Check for compatibility with existing conduit or cable systems regarding the slip-on cover mechanism.

Selection Notes

Select this model when a robust, weather-resistant pathway for cables is required in both indoor and outdoor environments. The 16-gauge steel construction offers durability against physical impact while the powder coating resists corrosion. The 12-inch length allows for modular expansion along cable runs. Consider the weight of 5.8 pounds for structural support requirements during mounting.

Part Context

This component belongs to the Hoffman wiring trough family, designed specifically for managing electrical cabling infrastructure. It serves as a protective channel rather than a full enclosure, focusing on cable organization and environmental shielding. The product line emphasizes ease of installation through embossed mounting holes and accessible cover designs.

Replacement Considerations

Ensure substitute parts maintain the same NEMA Type 3R rating and internal cross-sectional area (4x4 inches). Verify that alternative materials match the 16-gauge steel thickness to preserve structural integrity. Confirm that the cover closure mechanism remains compatible with existing maintenance procedures.
