The Hoffman Enclosures Inc. F4490EIN is a wireway elbow fitting designed for continuous cable runs with 90-degree turns. It features an inside opening configuration and fits 4.00 x 4.00 inch wireways. Constructed from 16/14 gauge steel, it includes a gray polyester powder coated finish. The unit measures 8 inches in length and width, with a height of 4 inches. Top and inside covers are removable to facilitate wire installation.
Verify the specific gauge requirement (16/14) matches your system design. Confirm the 4x4 inch dimension compatibility with existing wireway sections. Ensure the Type 1 rating aligns with the environmental conditions of the installation site. Check that the gray finish meets aesthetic or corrosion requirements.
Select this component when a 90-degree directional change is required in a 4x4 inch wireway system. The inside opening design allows for easier cable routing compared to outside bends. Consider the steel construction and powder coat finish for durability in standard indoor environments requiring NEMA 1 protection.
This part belongs to the Hoffman F40PF series of wireway accessories. It serves as a connector fitting within the broader enclosure and raceway ecosystem. The product is categorized under wire duct and raceway accessories, specifically designed for structural connectivity in electrical distribution networks.
