These aiders will help you get more height than traditional climbing sticks alone. The rope is 7/32" thick, as strong as amsteel, & offers over 2500 tensile strength. The EZaider Lite is constructed with a very stiff rope that retains memory. The heavy-duty hosing at the base of the step also helps keep the loop open for easier access to rest your foot, plus the snug fit to the rope gives you extra grip with no slip.
