ICC’s ladder rack runway straight sections are designed to support horizontal cable running overhead. Constructed of heavy-duty 16-gauge steel with a durable powder-coated finish, they can be easily attached to all racks. Two 5-foot long runways come packaged in a double-layer, tough carton. The runways can be joined together using butt splices which are sold separately. When joined together, the two 5-foot long runways make 10 feet. The runways can also be attached to the top of a floor mount rack using a relay rack bracket which is sold separately.
