Tool Storage Systems require only 21.52 sq. ft. of floor space and provide 172.22 sp. ft. of storage space. There is no need to attach it to the floor, as it stands firmly on its own. There is a caster on the lower edge of the panels which makes them easy to move. The load capacity is 220 lbs/panel. A maximum of 10 panels can be attached to the tool storage system. Use with Sovella pegboard hooks (sold separately). FOB Shipping Point.
