Sound damping materials under the shelves reduce shelf vibration & 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 & to transport heavy loads. Welded construction provides maximum strength & durability, & 5" casters are load rated at 125 lb. each. Double-sided truck also features smooth rounded handles & perforated end panels.
