Climbing rope has never been easier. The Ninja Foot Ascender by Harken Industrial is lightweight and durable. The housing is aluminum and the rope-holding dual cams are stainless steel.
Foot ascenders use your body’s largest muscle group to ascend a rope easily and quickly.
The Ninja is designed with springs that reduce rope drag to the lowest of any available foot ascender. This means that there is a smoother and easier take off without having to counterweight the rope or reach down to pull the rope through the unit. The result? Increased worker productivity.
The entry fairlead maintains correct rope alignment. Unlike every other foot ascender on the market, Harken Industrial’s dual cam system, based on Harken’s marine Cam-Matic ball bearing cleats, applies pressure to both sides of rope simultaneously.
This provides more thorough holding power and even force than competitive designs whose cams act on just one side of the rope against a fixed wall on the other side. Other foot ascenders use an aggressive barbed single cam that can create additional drag on the line or damage the rope cover.
The Ninja Ascender uses a transverse ribbed cam instead of barbs and the dual cam design prevents accidental kick-outs. It is also the first foot ascender that can work on either foot, and has fully adjustable straps.
