Vertical 3-tier shelving conserves floor space while creating organized storage for bins, tools or cleaning supplies. The PP construction forms sturdy shelves, each supporting up to 100 lbs, for a total capacity of 300 lbs. About 14.5-in clearance between tiers lets you place taller items, while crossbars underneath and side reinforcements help the frame stay stable. The waterproof, anti-crack, anti-slip surface suits garages, basements, kitchens or laundry rooms, and tool-free assembly speeds setup.
