Two Nite Ize CamJam cord tighteners with 8 ft (about 2.4 m) of rope. The CamJam is a knot-free way to tighten and secure light loads. Made of sturdy plastic, it has a carabiner clip with a stainless steel gate on one end and a rotating, ridged cam on the other. Clip the carabiner to a hook, D-ring or loop, feed the cord through the cam, pull to the tension you want, and the cam locks it until you rotate it to release. You can also clip it to one end of the cord to make a loop for bundling sleeping bags, blankets or cut brush. Use it to pitch tarps and tents, hang a washing line or bear bag, and tie light loads to trailers, bikes and boats. It fits cord from 2 to 5 mm.
