The Hoffman F22WN1 is a 2.5-inch Nipple Type 12 Indoor Feed-Through Wireway component manufactured by nVent Hoffman. Constructed from mild steel with a gray powder-coated finish, this accessory measures 2.50 x 2.50 x 1.00 inches. It is designed for use with NEMA 12 enclosures and wireway sections. The unit functions as a feed-through nipple to adjust wireway length between adjacent sections or fittings.
Verify the specific dimensional requirements of 2.50 x 2.50 x 1.00 inches against your enclosure layout. Confirm compatibility with existing NEMA 12 wireway sections. Ensure the mild steel powder-coated finish meets environmental standards for your installation site. Cross-reference the manufacturer part number F22WN1 with official nVent Hoffman documentation to confirm current specifications.
Select this component when extending wireway runs within NEMA 12 rated enclosures. The 2.5-inch size must match the cross-section of the connected wireway. Consider the indoor application scope due to the standard powder-coated finish. Verify that the feed-through configuration aligns with the required cable management path geometry.
This item belongs to the Hoffman Enclosures F20 series accessories. It serves as a structural connector for wireway systems rather than an enclosure body. The product is categorized under mounting brackets and flange enclosure accessories. It supports panel preparation by facilitating organized cable routing paths.
Consult official nVent Hoffman catalogs for direct substitute part numbers. Generic nipples may not maintain NEMA 12 rating integrity. Verify thread and dimension compatibility before substitution.
