One rack covers a 48 by 24 inch patch of floor and returns five full-depth tiers, each rated for 400 lbs and 2000 lbs together. Tier spacing moves in 1.5-inch steps, so the bottom bay can be set tall for a shop vacuum while the upper bays stay tight for stacked file boxes. The 72-inch height clears most garage door tracks, and connectors are built into the posts if a second unit gets added later. Setup uses the included hammer and gloves, no drill or wrench, and the 47.5 lb frame stands on its own once the shelves lock in. Wire tiers keep dust from collecting the way it does on solid boards, which matters for garden tools and paint that sit untouched for months.
