Our new design has already proven itself in field applications across the country. The large 4” x 6” cable boxes are actually the frame of the rack and are open top and bottom to allow cable entry. The mounting angles are bolted into the side of the unit, this can be shortened in order to accommodate two servers on the large base of the controller rack. Extended mounted rails with cable cutouts are available to support equipment at the rear, cable rings, protect and guide your cables with the rack. The controller rack is offered in 3 heights 70”, 77” and 84”.
