The jet Rack® step ladder storage system can store in the unused space on the ceiling or wall of your vehicle or storage room with this easy-to-use tension securing storage system. The JET Rack® stores A-frame step ladders up to 10 feet in length that have “tool holes” in their top plastic shelf or cap. For mounting, a 7/8" deep Unistrut type hanger rail, not included, is mounted to the flat surface where you want to mount your JET Rack®.
