Tree trunk protector straps are used when you are anchoring to a tree to protect not only the tree from ring barking but also your cable from unnecessary stress.
When using a tree as an anchor point in a recovery situation, wrapping cable, rope or chain around it causes damage to both your equipment and the tree. This means next time you may not have a viable anchor point for recovery.Keep your anchor point unharmed and able to be used again by you or a fellow 4wder with tree trunk protectors.
