Maximize your locker space with the Tools for School locker shelf. Fits into most standard sized lockers with easy adjustment of both width and height. Magnets on the side of the shelf affix to the inside wall of a metal locker, providing additional stability and preventing the shelf from shifting and shaking. This will also help to support up to 40 lbs. of weight, allowing safe storage of books, bags and other heavy items. Two or more locker shelves can be stacked on top of each other, with the legs of the top shelf inserting into the bottom shelf. Available in black, blue and magenta. Mix and match with other locker accessories available from Tools for School, including the Locker Drawer, Magnetic Pencil Holder, and Magnetic Locker Mirror. This item is patented.
