The Project Source 5-tier boltless steel shelving unit can be assembled vertically as a 72 in. high freestanding shelving or as two individual 36 in. high workbenches. Five adjustable particle board shelves can support up to 800 lbs. per shelf with the weights evenly distributed, enabling you to store a large number of household and personal items. The product is made from powder-coated finish for resistance to stains or corrosion and also includes 3/8-in. particle board decking for smallest sized articles. The shelves are adjustable in 1-1/2-in increments to accommodate your storage needs. Boltless design provides easy and quick assembly and no special tools are required. Plastic feet make the unit more stable and protect flooring from indentations or scratches, and also ensure ease of movement.
