Notch Jet Step Foot Ascender

The Notch Jet Step's unique dual cam design results in lower spring tension and reduced drag. Toothless cams eliminate virtually all rope wear and provide increased grip strength on wet, muddy and frozen ropes. Lower drag from decreased spring tension provides efficient self-tending of the climbing line. Ambidextrous - use on either left or right foot. Rope capacity 5/16 in. to 1/2 in.
