Yates - Scream Aids
Yates 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. Yates' original Screamers were first developed over ten years ago, designed to be used on less-than-ideal climbing protection such as small nuts, old 1/4" bolts, snow anchors, ice screws, or marginal protection. Screamers are designed for one-time use.
The Scream Aid can effectively reduce peak loads by 1.5-2kN. Activation: >1.5kN. Runner Strength: 7kN. Use on extremely marginal aid placements only.
