When is rope more than rope? When you fortify it with Nite Ize CanJam XT Aluminum Rope Tightener. Fabricated from durable cast aluminum, the CanJam® XT incorporates a carabiner with a cam mechanism to connect, tighten and secure your cargo. It includes both a loop and fixed-end system, providing two attachment options to tie down your light, medium and heavy cargo. Turning the cam lock lever adjusts tension levels, then locks to stay in place until you release it. Every CanJam® XT aluminum rope tightened includes a ten foot rope.
