Adding more shelves to your shelving unit allows you to make optimum usage of the cubic footage in each unit. Wire shelves admit more light to shelves below and allow greater air circulation than solid shelving. Shelves have all welded construction with additional wire trussing for greater strength. Top level wires run front to back for ease of loading and unloading product to and from shelves. Each shelf comes with plastic post sleeves and has a capacity of 800 lbs. per shelf.
