When you're stocking water for a household or small office, one or two bottles on the floor isn't enough. This four-tier rack holds eight 5-gallon or 3-gallon water bottles in a double-row layout, with a combined capacity of 335.1 pounds, so a full restock fits in one 25.6 by 13 inch footprint standing 42.9 inches tall. The frame is cast iron with a powder-coated finish that stands up to rust, corrosion, and the occasional drip without staining or peeling. Adjustable slots fit both 3-gallon and 5-gallon bottles, and high guardrails with shelf grooves keep every bottle from sliding or tipping. Built-in handles make it easier to lift a heavy bottle onto an upper shelf, and adjustable feet with an anti-tip design keep the rack steady on uneven floors. The rack is detachable, so tiers can be reduced if you don't need all four. It works well in a kitchen, office, garage, or storage closet.
