Made specifically for high-angle rescue work, the Rescue 8s versatile design and features fit the job its designed for. Extended horns on upper portion of large ring prevent the rope from sliding up and locking off. Large upper oval allows use of large and heavy-duty ropes. Dual tie-in holes keep Rescue 8 attached to harness while rope is tied to carabiner--no possibility of dropping during life-threatening situations. Made of hot-forged 6061 T-6 aircraft-quality aluminum and hard-anodized for durability, lower rope friction and a breaking strength of 10,000 pounds.
