Quickly and easily create a wall mounted shelving unit in your garage, basement, shed, or wherever else desired. This kit delivers a total of four 12" tall shelves and two 16" tall shelves. Once the top shelf is hung, the remainder of shelf hangers are each hung from the one above it with the simple hook through construction. With only two wall attachment points for the entire rack of shelves, the only tools required are a drill, 3/16" drill bit, screwdriver, and 1/2" wrench. The shelf hanger kit includes eight 12" wide X 12" tall Shelf Hangers, two 12" wide X 16" tall Shelf Hangers, two 12" wide Wall Mount Shelf Hangers, two 5/16" lag screws, and 28 hanger clips w/ mounting screws. Please note that shelf boards are not included. Home center stores such as Lowes and Home Depot will rip plywood shelves at minimal or no charge.
