Retention strap stabilization device

Abstract

A Retention Strap Stabilization Device is provided that improves the safety and longevity of retention straps used to secure cargo in transportation. The Retention Strap Stabilization Device has a foil body and a strap retaining slot, where in use, the foil body effectively lengthens the trailing edge of a retention strap thus changing the resonant frequency of the retention strap to prevent oscillation of the retention strap while in use on a moving vehicle. The device is held in place by a plurality of retention grips that embed themselves in the retention strap. The device not only prevents damage and resulting breakage of retention straps and the associated safety implications, but also reduces the potential for damage to the cargo being secured by the retention straps when unwanted oscillations of retention straps occur during transit.
