Meadow Burke’s BBS-Wall Plate Assembly is for use when the BBS-54 or BBS-27 Overhang Bracket must be attached to a vertical concrete section. The BBS-Wall Plate Assembly has two pieces, item 1 + 2 and will bolt into a cast insert or drill-in anchor which will allow the overhang bracket to be secured to the vertical wall. Simply place the Wall Plate Bolt through the first hole in the Overhang Bracket and through the welded pipe in the wall plate assembly. The Vertical Leg Bolt is then in the second hole. Use a minimum 3/4 inch diameter X 6 inch cast insert as an anchor.
