The Hoffman Enclosures AFDF1818P is a flush-mount door frame designed for use with screw-cover pull boxes. It features an 18.00-inch by 18.00-inch enclosure size compatibility, providing a 20-inch wide by 20-inch high cover opening and a 15-inch wide by 15-inch high door opening. Constructed from steel with an ANSI 61 gray polyester powder-coated finish, this component serves as a replacement or accessory for Type 1 pull boxes in indoor environments.
Verify that the target pull box is a screw-cover type compatible with 18x18 inch dimensions. Confirm that the required finish matches the standard ANSI 61 gray. Note that this item is a door frame only and does not include the back panel or the main enclosure body. Ensure the application environment is indoor, as Type 1 ratings do not support outdoor exposure.
Select this part when replacing a damaged door frame on an existing 18x18 inch pull box. It is suitable for indoor telecommunications and signal distribution applications requiring Type 1 protection. Do not use for outdoor installations or where higher ingress protection ratings are mandated. Verify mounting hole patterns if retrofitting to non-standard boxes.
This component belongs to the Hoffman pull box accessory line, specifically designed for communication infrastructure. It complements the main enclosure bodies by providing a secure, flush-mounted access point. The product is manufactured by nVent Hoffman, specializing in industrial enclosures and electrical hardware solutions.
Compatible substitute frames must match the 18x18 inch internal dimension and 20x20 inch external cover size. Ensure the material thickness and latch mechanism align with the original box specifications to maintain structural integrity and security.
