These Magnetic Tool Cribs make great storage solutions and give you extra space where you need it the most! Place them against your steel tool box, our tool panels or under the hood to hold onto all your fasteners and tools. The heavy duty steel bins have huge magnets (coated so they won't scratch paint) that hold them firmly in place! Chemical resistant, powder coated red...of course. All tool cribs are 4 1/2" deep, 1 1/8" high, and come in four different lengths, 5 7/8"; 8 1/8"; 10 1/2"; 12 1/8".
