Multi-functional energy absorbing device. Screamers will provide added protection in climbing and rescue situations. Screamers not only absorb energy directly because of the stitch ripping effect, they also allow your rope to absorb more energy from the fall by increasing the time interval of the fall. Screamers can reduce shock loading in any rescue system. The standard Screamer can effectively reduce peak loads by 3-4kN in any climbing or rescue system. YATES original Screamers were first developed over ten years ago, YATES has since developed numerous variations on the Screamer design for use in Aerospace, Military and explosive testing for the deceleration of objects. Screamers were originally designed to be used on less than ideal climbing protection such as small nuts, old 1/4 bolts, snow anchors or marginal protection. We have determined that the most effective activation for a standard screamer to be 2kN550lbf. for climbing related situations.
