"Designed for lighter loads, the knot-free Nite Ize CamJam Cord Tightener is great for bundling, tightening, tensioning, securing, hanging, and wrapping. The CamJam locks securely into place with a simple pull of a cord. No knots to tie or untie. Simply anchor the carabiner to any hook, loop, or D-ring and feed your cord through the cam until you've reached the desired level of tension. Another pull and the cam locks into place and stays that way until you release it by rotating the cam. Constructed of rugged, durable plastic, the Nite Ize CamJam Cord Tightener features a carabiner clip with a stainless steel gate at one end, and a rotating, ridged cam mechanism at the other. It's easy to adjust and readjust, time after time. Use it to hang or secure tents, tarps, blinds, and gear. Use it to bundle sleeping bags, blankets, cut brush, and other light loads to wheelbarrows, boats, wagons, bikes, and dollies. 2 attachment methods: loop system and fixed end system Sturdy, durable plastic Lightweight but strong construction Fits cord sizes 1/16"" - 3/16"""
