Trunk Anchors

This page compares Anchors that are placed on the tree trunk. Note that the False Crotch and Floating Anchor are covered on this page:

There are many possible anchors in our ‘toolbox’, but for the most part, JRB uses only 4 anchors. Each climber must take responsibility for their own decisions and actions, based on their knowledge, experience and comfort level. Our life is on the line; do not experiment with your life and ensure that you are 100% certain of what you are tying and what you are tying it with. Note: the Running JRB Hitch is intentionally NOT on this list, given that the (newer) Maverick Hitch is preferred.

  • JRB Cinch (JRBC)

Six Retrievable Tether or Rappel Anchors

The Anchors

1. Maverick Hitch (MAV)

This is JRB’s preferred anchor for climbing methods that involve advancing an anchor up the trunk, including JRB Hitch Climbing and Stick Climbing. This is the most versatile solution given that it can be advanced above us with a pole, or pulled up using the Houdini rigging. Unlike the JRB Hitch which fully explodes off the tree, the Maverick leaves a strand of rope around the tree after it is released and will not drop to the ground if there are branches. Therefore, the climber must ensure that there is nothing on the end of the rope that would cause it to get hung up as we pull it down. If the Maverick Hitch is being used as a basal anchor, the rope should be wrapped around the trunk twice and securely cinched in a horizontal fashion.

2. JRB Cinch (JRBC)

Specifically designed for climbers who are not comfortable tying knots at the climbing site, and used in methods like JRB Hitch Climbing and Stick Climbing, the JRB Cinch is an alternative to the Maverick. Advantages: Given that it does not need to be tied at the climbing site, it is easier to affix. It is also easier to use when navigating branches. It is easier to remove the Maverick Pole from a Cinch than a Maverick. Disadvantages: Metal on metal noise is possible if the pole contacts the ring or carabiner. Retrieval requires more effort and has more complexity, sometimes requiring a JRB Cinch to be removed from the rope, requiring reconstruction before the next climb. Building a double sided system requires slightly more rope than Maverick Systems. If the Maverick Hitch is being used as a basal anchor, the rope should be wrapped around the tree twice and securely cinched in a horizontal fashion. The JRB Cinch (and video links) are detailed on a dedicated page:


3. JRB Hitch (JRBH)

The JRB Hitch has to be manually set and cannot be advanced with a pole. However, it’s the easiest anchor for remote retrieval because it explodes off the tree, leaving no strand around the tree. JRB prefers it for a Basal Anchor when executing SRT in certain situations. JRB also prefers it as a Rappel anchor if setting a rappel line manually at the top of a climb (and there is not already a Maverick or JRB Cinch in place, or there would be difficulty retrieving it).

4. Saddle Hunter’s Hitch (SHH)

The Saddle Hunter’s Hitch is the best option when setting the anchor manually and wanting it to be as high up on the trunk as possible. JRB uses it when a pole is not available, or for temporary applications where the hitch is manually removed. It is also EEL (either end loadable) and valuable in certain rigging and rescue scenarios. Some hunters use the EEL feature to hang a backpack from the unused side. Even though there is a remote retrieval variant published, JRB does not prefer the SHH in those scenarios, with preference for one of the options above. The SHH is not the best choice for a basal anchor given that it can’t be seen by the climber and therefore cannot be monitored for potential changes/loosening after cyclic loading.
