SP-series of blank rack panels for 19-inch wide EIA racks are made with 18-gauge certified US steel and have a 0.500-inch flange for strength and rigidity. Two of these panels are mounted to the front of Lowell floor racks to provide extra support during shipping. They can then be removed and placed in the top of the rack to close the top opening. SP-series panels have a durable, black wrinkle powder epoxy finish. Available as single units or multi-pack cartons.
