Dual cam system (based on Harken’s marine Cam-Matic® ball bearing cleats) applies pressure to both sides of the rope simultaneously. This provides more thorough and even force than competitive designs whose cams act on just one side of the rope against a fixed wall on the other side.
The Ninja uses a transverse ribbed cam as opposed to other designs that rely on aggressive barbs that are known to damage rope.
The dual cam system prevents accidental kick-outs. The rope stays in place until the user is ready to release it intentionally. The Ninja is the only foot ascender that can be used on either foot.
