The BP-D is a single-piece, powder-coated steel backplate designed to accommodate two MP or MPX enclosures, two Magnum inverters, and two inverter hoods together; making the complete system appear more seamless. Designed with PEM (i.e. internally threaded) nuts, the backplate is shipped with ¼-20 x ¾” Hex head bolts for easily mounting the MP enclosure, a Magnum inverter, and the inverter hood.
