The Wire Shelving Units are an all-in-one package that includes shelving and Quantum’s extra large RACKBINS. Each bin offers 42" in length making them ideal for storing large items. Each bin can sit on a 42" shelf where it wastes no space. The wide stacking ledge and anti-slide lock keeps bins in place at all times. Eight 1/4" hole templates on the bottom of bins provide an easy means to drill holes for either drainage or ventilation purposes.
