The Hoffman F44T118GVP is a NEMA Type 1 straight wireway section designed for electrical wiring protection. It features a 4x4 inch cross-section and an 18-inch length, constructed from galvanized gray steel with a polyester powder coated finish. The unit utilizes a lay-in flat cover design, allowing one side to remain open for easy wire insertion. It meets UL 870 and CUL standards, ensuring compliance for indoor applications where exposure to dust, dirt, oil, and water is not severe.
Verify that the specified NEMA Type 1 rating aligns with the environmental conditions of the intended installation site. Confirm that the 4x4x18 inch dimensions fit within the planned conduit or wireway layout. Ensure compatibility with existing Hoffman wireway accessories and fittings. Check local electrical codes for any specific requirements regarding steel wireway grounding and support spacing.
Select this model when a straight run of moderate width is required for organizing multiple conductors. The galvanized gray finish suits environments where aesthetic uniformity with other Hoffman components is desired. Consider this option for projects requiring UL 870 certification. Evaluate whether the flat cover style meets accessibility needs compared to hinged alternatives.
This component belongs to the Hoffman wireway product line, which includes various sizes and configurations for electrical infrastructure. It is manufactured by Hoffman Enclosures, Inc., now part of nVent. The product series focuses on providing standardized solutions for cable management in controlled indoor environments.
Direct substitutes include other Hoffman straight sections with identical 4x4x18 inch dimensions and NEMA Type 1 ratings. Verify that alternative models maintain the same galvanized gray steel material and lay-in flat cover mechanism to ensure seamless integration with existing installations.
