Ken Tool has expanded its line of tire restraining devices with the new 36010 5-bar Super Magnum cage. The Super Magnum cage reduces the side-force energy resulting from a catastrophic sidewall zipper rupture of a super wide tire by 93%, according to the manufacturer. Additional features include five mandrel-bent, high-strength 12 gauge, 2-1/4-inch diameter structural steel tubes, welded to a 3/16-inch thick steel plate base with a two-inch wide, ¼-inch thick reinforcing strap welded to the tubes.
