“ Incredibly useful item! I have been using it just about any time I need to pull a rope but I'd prefer to have a handle. This particular one is well made, grips securely, and advances smoothly. Having two lower attachment holes instead of one provides for additional flexibility in use. My only complaint is that the cam mechanism cannot be locked open and that it takes two hands to open the cam when no rope is present in the device. It would have been helpful if the mechanism operated similarly to the CMI foot ascenders. This is what I expected when I ordered the item, but the catalog photo shows the ascender from the backside and provides zero clues on the operation of the cam. ”
