For the highest quality rack system choose the Middle Atlantic 19" Relay Rack. Constructed with 11-gauge 10-32 threaded steel side channels, this rack can handle up to 400lbs of equipment and cabling. Incorporating a self-squaring, self-leveling design greatly reduces assembly time. Unique gusseted base means no shimming on uneven floors. The optional cantilever support base adds stability when installing deep equipment.
