The Hoffman F44GCPNKGV is a galvanized steel closure plate designed for Type 1 indoor lay-in wireway systems. It measures 4 inches by 4 inches and features an unpainted finish. The component complies with UL 870, CUL, and CSA C22.2 standards, providing NEMA 1 and IP30 enclosure protection. Constructed from 16/14 gauge steel, it serves as a termination fitting to seal the ends of wireways without knockouts.
Verify that the required configuration matches the specific part number suffix. Confirm whether knockouts are needed; this model lacks them. Ensure compatibility with existing 4-inch square wireway dimensions. Check for applicable regional certifications such as UL or CSA if mandated by local codes.
Select this component when a sealed end cap is required for standard 4x4 inch wireway installations. It is suitable for indoor environments requiring NEMA 1 protection against falling objects and limited dust ingress. Choose this over painted variants if an unpainted galvanized appearance is acceptable or preferred for specific aesthetic or grounding requirements.
This closure plate belongs to the Hoffman lay-in wireway fitting series. It functions as a terminal component to complete wireway assemblies. The product line supports various enclosure sizes and materials, ensuring standardized termination solutions for industrial electrical infrastructure projects.
Direct substitutes include other manufacturers' 4x4 inch galvanized steel closure plates for Type 1 wireways. Verify dimensional accuracy and material gauge equivalence. Ensure replacement parts meet identical UL 870 and NEMA 1 certification standards.

Choose logic inverter ICs by thresholds, supply, output drive and delay. Compare standard and Schmitt-trigger inputs, power sequencing and replacement checks.
