The Hoffman A73P21N is a steel backplate designed for free-standing, Type 1 one-door enclosures. It fits enclosure sizes of 84 inches by 25.5 or 26 inches. The panel measures 73.16 inches in width and 21.5 inches in height. Constructed from 12 gauge steel, it features a polyester powder paint finish with a white color. This component serves as a structural backing for large single-door industrial enclosures.
Verify the specific enclosure model compatibility, noting that this panel fits 84-inch wide units with depths of 25.5 or 26 inches. Confirm the requirement for 12 gauge steel construction and the white polyester powder coated finish matches the intended installation environment. Ensure the application involves free-standing Type 1 enclosures to guarantee proper fit and function.
Select this part when replacing a damaged backplate for a large free-standing Type 1 enclosure. The 12 gauge steel material provides necessary structural support. The white powder coat finish offers standard protection. Verify the enclosure depth is compatible with the 25.5 or 26-inch specification before procurement.
This component belongs to the Hoffman series of enclosure panels. It is specifically engineered for large free-standing Type 1 enclosures. The design supports standard industrial applications requiring NEMA 1 protection levels. It functions as a replacement or new build component for single-door configurations.
No public confirmed substitute part numbers are available.
