Double-sided truck features three double-sided slanted shelves (six shelves total) so you have storage on both sides and move twice the materials as single-sided trucks. Each shelf measures 35" wide x 6-3/4" deep. The distance between the shelves is 12". Sound damping materials are applied to the underside of shelves to reduce vibration noise. 5" casters (two with locking brakes) make it easier to cross thresholds and to transport heavy loads. Welded construction provides maximum strength and durability, and 5" casters are load rated at 125 lb. each. Double-sided truck also features smooth rounded handles and perforated end panels. Durable all-steel construction contains recycled material.
