This is by far the most heavy duty shelving on the market for your 5 gallon dispensers! Two 5 gallon cubes will fit on each shelf! Capacity per shelf is 100 lbs. 24" long by 18" wide, and 78 " high. 5 shelves with lip, 4" caster wheels, two of them locking. This piece of equipment will last for years (probably decades!).
