Ever done a really long rappel with a heavy pack? Remember death-gripping the rope and praying for it to end? The Carabiner is specifically designed to make grueling rappels more comfortable. Use the Freino with your belay device like normal. When you get further down the line and it's getting harder to hang on, just re-direct your break hand through the spur to increase the friction for a nice controlled descent. *For use with single ropes only.
Bottom Line:
Make rappelling easier with the Petzl Freino Carabiner.
