Raven is a compact, multi-purpose rigging device designed to replace several single-function tools with one piece of aluminum hardware. The Raven can serve as:- Toggle- TRP (Transient Rigging Point)- Releasable block- Jester-style rigging- Throttle rappel device The Raven Advantage:Many canyoneers carry up to three separate devices to cover these functions (e.g.,a toggle, a figure eight for releasable blocks, and a GiGi-style device for TRRPs).Raven consolidates those capabilities to simplify your kit and reduce carriedweight. Material Advantage:Raven is made from aluminum, so it is not subject to the same breakage risk asplastic toggles. *Designed to be used with 8 mm rope and 6-7 mm anchor cord for retrievable rigging. Some rigging options can use 9.5 mm rope if the rope is supple. For other rigging scenarios 9mm is a bit thick even if supple.
