Klein 54474 Mid-Size 4-Box Slide Rack

4-Box Slide Rack. Holds four Klein mid-size storage boxes. Boxes not included with rack, must be ordered separately. Welded, extra-rigid, all-steel construction. Metallic-gray, baked-enamel finish. Boxes ride in and out on heavy-duty channel tracks that permit covers to open all the way for full access. Heavy tabs prevent boxes from being accidentally pulled out, yet allow boxes to be easily removed when desired. Locking bars can be readily attached to prevent unauthorized access. Dimensions: 15-1/4"x11-3/4"x10-3/4" ( 39 cm x 30 cm x 27 cm).
