The Hoffman Enclosures Inc. F44T172GVWK is a straight section wireway designed for electrical cable management. It features a galvanized steel construction with an unpainted finish, ensuring durability and corrosion resistance in industrial environments. The unit measures 4 inches by 4 inches in cross-section and has a length of 72 inches (6 feet). It is classified as NEMA Type 1, providing protection against falling dirt and limited ingress of solid foreign objects. The design incorporates a lay-in style assembly, allowing for easy installation without the need for tools to secure the cover. This component is UL and CUL listed, meeting specific safety standards for wiring troughs.
Verify that the required NEMA Type 1 protection level aligns with the installation environment's exposure to dirt and debris. Confirm that the 4x4 inch cross-section accommodates the total volume of cables being routed. Ensure compatibility with other Hoffman wireway fittings and accessories for a continuous run. Check local electrical codes regarding grounding requirements for galvanized steel wireways. Validate that the 72-inch length fits the planned layout constraints.
Select this model when a standard straight run of wireway is needed for indoor applications requiring basic environmental protection. Consider the galvanized finish for general industrial settings where moisture resistance is beneficial but not critical. Evaluate the 4x4 inch capacity against the maximum fill percentage allowed by applicable electrical codes. Compare with alternative lengths if the 72-inch size does not match the specific span requirements of the project.
This part belongs to the Hoffman Lay-In NEMA Type 1 Galvanized Wireway series. It is designed to integrate seamlessly with other components from the same product line, such as elbows, tees, and reducers. The series offers various sizes and lengths to support flexible system design. As a straight section, it serves as a fundamental building block for creating structured pathways for electrical conductors in commercial and industrial infrastructure.
Direct substitutes include other manufacturers' NEMA Type 1 galvanized wireways with identical 4x4x72 inch dimensions. Verify that any replacement maintains UL or CUL listing for code compliance. Ensure the lay-in cover mechanism is compatible with existing mounting hardware. Cross-reference part numbers from distributors like Graybar or Fromm Electric Supply for equivalent stock items.
