    Used to cover flange cutouts in disconnect enclosures when disconnects are not installed. This greatly increases the versatility of disconnect enclosures, enabling them to also be used as regular Type 12 enclosures. If the UBP model is used, the disconnect enclosure can be used as a regular Type 4 enclosure. Hoffman adapter plates are made from heavy gauge steel and have an oil-resistant gasket to maintain a dust-tight and oil-tight seal. Mounting hardware and instructions are included. Door hardware is not furnished with blank adapter plate. Door hardware must be ordered separately from the disconnect manufacturer when using catalog numbers A22BAP on Bulletin A22 Enclosures and A3456BAP on Bulletin A25 Enclosures.
