The Redesigned Ninja Foot Ascender by Harken Safety & Rescue is a lightweight, high-performance rope ascender engineered for arborists, rope access technicians, rescue professionals, and industrial climbers.

Designed to maximize efficiency and reduce rope drag, the Ninja uses an innovative dual-cam system to provide smoother ascents, improved productivity, and reduced fatigue.

• Dual Cam System: Independent articulation maintains proper alignment for secure engagement and climbing efficiency
• Low Rope Drag Design: Integrated springs allow smoother take-off and faster ascent
• Rope-Friendly Cam: Ribbed profile reduces sheath damage
• Anti Kick-Out Sidewalls: Keeps rope securely engaged until intentional release
• Ambidextrous Fit: Works on either foot. Closed fairlead keeps rope in place and prevents snagging
