The Chain Reactor is a excellent PAS (personal anchor system) that easily attaches to your harness and allows for multiple tie-in lengths throughout your canyon descent. A versatile alternative to your standard daisy chain. Each individual nylon loop of the chain reactor is constructed to test at full strength, making it ideal as a saftey prior to descent in a canyon, clipping in at the top of a climbing pitch, using it as an anchor, or in a rescue pick off.
