INCREASED PRODUCTIVITY
The Ninja™ is designed with less spring force for the least rope drag of any available foot ascender. This means that there is a smoother and easier take off without having to counterweight the line or reach down to pull the line through the unit. The result? Increased worker productivity.

INNOVATIVE DESIGN
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 holding power than competitive designs that press just one side of the rope against just one side of the ascender’s wall.

WORKS ON EITHER FOOT
The Ninja is the only foot ascender that can be used on either foot.

WON’T DAMAGE YOUR ROPE
The Ninja uses a transverse ribbed cam instead of teeth. Competitive designs rely on aggressive teeth on their single cams, which can damage rope cover.

ACCIDENTAL KICKOUTS ARE A THING OF THE PAST
The dual cam system prevents accidental kick-outs. The rope stays in place until the user is ready to release it intentionally.
