Manually locking carabiner. Particularly intended for attachment to the belay and belaying directly from the anchor point. The pear shaped design and round cross section of the Attache also give excellent ease of use for belaying with a Munter hitch. A compact carabiner, it is easily operated with one hand and its light weight makes it the ideal companion for mountaineering as well as rock climbing. Each manual, screw lock, lightweight carabiner is etched in white with HERA Climb4Life. PETZL donates 1.00 from the sale of each carabiner to the HERA Foundation. We're so proud to have been given this tremendous honor. The work that The HERA Foundation does is truly incredible. It's great to be part of it, says John Evans.The HERAbiner is a vehicle to raise funds and awareness, but it also builds community think of it like a Lance Armstrong Live Strong bracelet that is rated to 5000 pounds. Petzl wins the HERA Power of One award for their generous contributions. Check out the story in Climbing Magazine. Note that this item of climbing safety equipment is non returnable.
