The Hoffman F22T12HC is a hinged cover wiring trough designed for indoor wire and cable management. Constructed from 14-gauge steel, it features an ANSI 61 gray polyester powder finish. The unit measures 2.50 inches in width, 2.50 inches in height, and 12.00 inches in length. It provides NEMA Type 1 and 12 protection ratings and holds UL 870, CSA, and JIC approvals. The design includes continuously welded ends and seams that are ground smooth, with no holes or knockouts.
Verify the specific dimensional requirements against the 2.50 x 2.50 x 12.00 inch specifications before ordering. Confirm that the NEMA Type 12 rating meets the environmental protection needs of the installation site. Ensure compatibility with existing panel layouts, as this unit lacks pre-drilled mounting holes or knockouts. Check for required UL 870 and CSA certifications if mandated by local electrical codes.
Select this model when continuous welding and a smooth interior surface are required to prevent wire damage. The NEMA Type 12 rating makes it suitable for environments where falling dirt and dripping non-corrosive liquids are concerns. The 14-gauge steel construction offers durability for standard industrial applications. Consider the fixed 12-inch length for short-run cable routing tasks.
This component belongs to the Hoffman F20HC series of hinged cover wiring troughs. It is manufactured by nVent Hoffman, a provider of industrial enclosures and cable management solutions. The product line focuses on protecting electrical connections within control panels and machinery.
Check for direct equivalents in the same F20HC series with identical dimensions. Verify that any substitute maintains the NEMA Type 12 rating and 14-gauge steel construction. Ensure the replacement also offers UL 870 and CSA approvals for compliance.
