Craftline Storage Systems' Heavy Duty Service Tray Box Racks are designed to hold large metal or plastic scoop compartment service trays. The cabinet drawers slide in and out with heavy duty ball bearing slides, and are manufactured with solid drawer bottoms for maximum drawer support. The tray racks are constructed from 22-gauge steel with a rust- and contaminant-resistant Black Texture Powder Coat finish. They are available with four or six drawers, and can be stacked with included hardware and coordinate with other products for modular capabilities. Coordinated base and leg sets are also available.
