nVent Hoffman P2APBMBK Plinth Base Mounting Bracket Kit The Plinth Base Mounting Bracket Kit secures to the cast aluminum corner blocks of the standard Plinth Base. The bracket kit serves two functions: the first function is to facilitate floor mounting, and the second is to run a grid network for cable management. Previously, it was challenging to secure an enclosure to the floor, but with the bracket kit the mounting holes are now easily accessible from inside the cabinet after gland plate removal. Grid straps can also now be mounted to the Plinth Base Mounting Bracket Kit to secure cables entering or leaving the cabinet through the base. Grid Straps and Plinth Base are sold separately. The brackets are constructed from a 10-gauge (3.0 mm) steel, and finished in RAL 9005, matte black.
