Designed to connect to the users harness and to a fixed surface or helo rappel point, via the unique aluminium snap hook. The lanyards length is adjustable due to the Yates adjustable daisy chain system and the adjuster buckle, which has a 6kN strength. Built with mil spec.5625 tubular webbing, the ultimate strength of lanyard tests over 3500lbf. (15kN) breaking strength. The Kong Tango double locking snap hook is classified to meet NFPA 1983/2006 edition standards. The Yates Screamer shock absorber is added for energy absorption. In the event an activation force of 2.5kN is exerted on the lanyard during a fall, the Screamer has the potential to absorb 2-3kN of energy if fully activated.
