This simple device lets you tension and secure cords quickly, reliably and without having to tie complex knots. Easy to adjust, it’s excellent for binding and tethering loose items, such as when lashing down tarps or bundling long materials.

With the carabiner-clip end anchored to a fixed D-ring, loop or grommet, you simply feed a cord (up to 4.75mm/3/16" in diameter) through the body and pull firmly until taut. The cam-action stop mechanism locks the cord in place, holding the tension applied so the cord stays snug until you release it by lightly pressing the stop.

About 2 1/2" long, it has a spring-loaded stainless-steel carabiner closure. Available in glass-reinforced nylon or cast aluminum. A 50' hank of 2.5mm diameter cord is available separately; it has a highly reflective material woven into it for greater visibility in areas where tripping is a hazard.
