Perfect for a garage, shop, basement, or store, the TRINITY Dual-Sided EcoSTorage Bin Rack is all about maximum storage. Small bins on top sort small pieces or screws and keep them easy to reach and visible. Larger bins on bottom hold bigger pieces or lots of frequently used screws. And a large powder-coated dual-sided steel rack keeps it all together, rolling on smooth 3-inch swivel casters, 2 of which lock in place. The whole 94-bin unit has a weight capacity of 330 lbs.
