Overview

The Hoffman Enclosures Inc. A121248RT is a Type 3R wire trough constructed from 14-gauge steel, designed for outdoor wire and cable management. Its dimensions are 12.00 x 12.00 x 48.00 inches (305 x 305 x 1219 mm). The unit features an ANSI 61 gray polyester powder paint finish applied over a pretreated surface to ensure durability in moisture-exposed environments.

Feature Summary

• Constructed from 14-gauge steel with a durable ANSI 61 gray polyester powder paint finish
• Designed for protecting wire distribution, junctions, and terminations in outdoor applications
• Provides protection against moisture exposure suitable for NEMA Type 3R environments

Applications

• Outdoor wire and cable distribution systems
• Protection of electrical junctions and terminations in moist environments
• Cable management for equipment exposed to weather elements

Procurement Notes

Verify the specific dimensional requirements and material gauge against project specifications before ordering. Confirm that the Type 3R rating aligns with the environmental conditions of the installation site. Ensure compatibility with existing mounting infrastructure and adjacent enclosure components. Check for any specific UL 870 compliance documentation if required by local regulations.

Selection Notes

Select this model when a robust, steel-based solution is required for vertical or horizontal cable routing in outdoor settings. The 12x12 inch cross-section accommodates standard cable bundles, while the 48-inch length provides substantial coverage. Consider the weight and mounting hardware requirements associated with 14-gauge steel construction during system design.

Part Context

This component belongs to the Hoffman wiring trough series, which offers various lengths and cross-sectional sizes for comprehensive cable management solutions. It is part of the nVent HOFFMAN product line, focusing on industrial enclosures and accessories. The Type 3R designation indicates suitability for outdoor use where rain and sleet protection is necessary.

Replacement Considerations

Compatible alternatives include other Type 3R wire troughs from the same manufacturer with similar dimensions, such as the A121260RT or A1212116RT, depending on length requirements. Ensure substitute models maintain the 14-gauge steel construction and compatible mounting configurations.
