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. Sound damping materials under the shelves reduce shelf vibration and noise when empty. Each shelf measures 35" wide x 6-3/4" deep. The distance between the shelves is 13". 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.
