The new SHORTY Screamer offers the exact same properties as the standard Screamer in a more compactly packaged unit.
Screamers have proven to be very successful in reducing loads to any anchor when it is stressed in excess of the activation force of the Screamer device.
When the Screamer activates, the action of the stitch ripping produces a loud tearing sound, indicating the system has reached the activation point of the Screamer(>2 kN). The activation point of a Screamer is consistently repeatable to +- 5% accuracy. (Screamers are very useful in documenting maximum loads in a given situation, such as their use in Rescue.) Screamers can be combined in series to double or triple the total absorption. Screamers can also be “ganged” to increase activation force and absorption.
