F4418SC

Overview

The Hoffman F4418SC is a screw cover wiring trough constructed from 14-gauge steel with an ANSI 61 gray polyester powder-coated finish. It measures 4.00 x 4.00 x 18.00 inches and meets NEMA Type 12 and IP55 standards for protection against dust, dirt, and dripping non-corrosive liquids. The unit features continuously welded and ground-smooth ends and seams without knockouts. It holds UL 870, CSA, and JIC approvals.

Feature Summary

• Captivated cover screws thread into sealed wells to maintain enclosure integrity
• Oil-resistant finish suitable for industrial environments
• Smooth welded construction eliminates gaps for enhanced contamination protection

Applications

• Protecting wire and cable distribution in industrial settings
• Safeguarding junctions and terminations in moist or dirty locations
• Enclosures where frequent access is not required

Procurement Notes

Verify the specific nVent HOFFMAN part number F4418SC matches your dimensional requirements of 4x4x18 inches. Confirm that NEMA Type 12 compliance aligns with your facility's environmental protection needs. Ensure the 14-gauge steel material specification is sufficient for your structural load expectations. Check for any regional certification requirements regarding UL 870 or CSA listings before finalizing procurement.

Selection Notes

Select this model when continuous welding and smooth surfaces are necessary to prevent debris accumulation. It is appropriate for applications requiring protection against dust and dripping liquids but not hose-directed water. Consider the 18-inch length for extended cable runs within standard control panels. Verify that the screw cover mechanism fits your maintenance access protocols compared to hinged or removable options.

Part Context

This component belongs to the Hoffman F-44 series of metal enclosures designed for electrical and industrial use. It serves as a specialized wiring trough rather than a full equipment cabinet. The product line emphasizes durability through welded steel construction and standardized protective finishes. It is commonly integrated into larger panel assemblies to organize and protect internal cabling infrastructure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should verify exact dimensional compatibility and material gauge when sourcing alternatives from other manufacturers.
