The Harken Ninja is the only dual cam foot ascender on the market.
By utilising your body’s largest muscle group, foot ascenders make ascending rope fast and efficient, but climbing rope has never felt easier than with the Harken Ninja Foot Ascender. The unique design applies even pressure to both sides of the rope simultaneously. This provides more holding power than when compared to conventional foot ascenders and helps to prevent accidental kick outs.
Further features of the Harken Ninja include:
The Ninja’s design significantly reduces rope drag. This feature is particularly useful during those first few steps off the ground when the line weight is low, meaning there is no need to counterweight the rope or reach down to pull the rope through the device.
