Are you a One Sticker, or are you looking for a way to use your tether as gear hanger? Then this is for you! These Tether Assist Hooks are designed to help you move your tether up the tree as you are one sticking. How it works is you just grab the hooks on the and pull them away from the tree to loosen the rope's grip on the tree. Then while grabbing the hooks still, you can pull the rope up the tree. You will just need two Tether Assist Hooks for this system to work.
The beauty of this system is how these can be used as a gear hanger once you get to hunting height. Just install a Celtic Button Slider Knot to keep your tether from loosening up, or any other method to lock your tether onto the tree.
