Looking to carry a Hi-Hat board on your Apollo cart? Check out the Inovativ Hi-Hat Rails, a two-rail set that mounts to the underside of the Apollo 40 or Apollo 52 equipment cart for easy and quick access. The rails install easily with six bolts to the dedicated threaded holes. The rails are made from rugged 5052 aluminum construction covered in a durable black powder-coated finish and provide access from either side.
