Ninja™ Foot Ascender

Ninja™ Foot Ascender

The Harken Industrial™ Ninja™ foot ascender makes an arborist’s job easier because it adds the least rope drag of any available foot ascender. This means that there are smoother and easier first steps because you don’t have to counterweight the line or reach down to pull the line through the unit – resulting in increased 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 than competitive designs that press just one side of the rope against just one side of the ascender’s walls. Other foot ascenders use an aggressive toothed 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 teeth 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.
