10. Be sure to rig your attachment point properly. Use a tree strap to protect the bark of a tree. When you put the strap around the tree or rock, hook both ends of the strap to the hook on the end of the winch line. This way the strap won't tighten like a noose around the tree and damage the bark. If possible, use a clevis to hold the tree strap ends together and/or a hook with a closing latch that keeps it all from unhooking while you winch yourself forward. If you use winch rope be sure you have a sleeve that protects it from rock abrasion.
