Harken Ninja Foot Ascender

Climbing rope has never been easier. The Ninja Foot Ascender by Harken Safety & Rescue 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 has a maximum working load of 1.5 kN (330 lb) and can handle rope up to 13 mm (1/2″). 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.

1. Accidental Kick-Outs 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. The Ninja is the only foot ascender that can be used on either foot.
2. Won’t Damage Rope: The Ninja uses a transverse ribbed cam as opposed to other designs that rely on aggressive teeth that are known to damage rope.
3. 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.
