This page is dedicated to the creation and use of a climbing system using the JRB Cinch as the trunk anchor.
The creation of the JRB Cinch itself (which can be used in other applications) is covered on a dedicated page. It is assumed that the climber already has a saddle equipped with a redundant bridge and carabiners on both bridges. Related info:
Videos
Effectively, this system is a variation of JRB’s Hitch Climbing System, simply using the JRB Cinch instead of the Maverick Hitch as the anchor. The following video demonstrates how a system is constructed, and how a hitch climb is executed.
The following video demonstrates how a One Stick Climb can be executed using a JRB Cinch System:
The videos below covers setting, advancing, retrieval, system creation and creating JRB Cinch Systems. We want to avoid removing friction hitch(s) during retrieval and need enough rope to pull the Cinch down to within reach of our hands when we are on the ground.
This video demonstrates how to navigate past branches when using the JRB Cinch with the Maverick Pole.
Retrieval Considerations
As demonstrated in the video above, we CAN attempt to use the Maverick Pole to retrieve a JRB Cinch, but we risk damaging the pole. Therefore, the climber must either accept the commitment to climb up to the cinch in order to retrieve it OR put the retrieval line on before advancing and setting it.
System Components
Building a system requires the following components, each of which is detailed in a section to follow. Make a shopping list and visit Ape Canyon for your purchases and make sure to use the JRB15 coupon code.
- A Climbing Rope
- A JRB Cinch on each end of the rope
- Cord for Two Friction Hitches
- A Retrieval Cord
- The Maverick Pole
- The Garda Hitch Footloop
1. Rope
In general, a 9.5-10 mm rope is recommended. Heavier climbers may prefer an 11 mm rope. Lighter climbers may prefer an 8 mm rope. See this page for details and rope recommendations:
Use this formula to calculate how much rope is needed. Note that this estimate is approximate; a larger tree diameter could affect consumption:
Length = (2 x Cinch Height) – 6′
These examples assume the cinch is set 6′ above the platform.
- Platform@17′, Cinch@23′: (23′ x 2) – 6′ = 40′
- Platform@22′, Cinch@28′: (28′ x 2) – 6′ = 50′
- Platform@27′, Cinch@33′: (33′ x 2) – 6′ = 60′
Bottom line: JRB recommends a minimum of 50′.
2. JRB Cinch
The details and items needed to create the JRB Cinch itself are covered here. Get components for 2 Cinches.
3. Cord for 2 Friction Hitches
The Compact Longhorn Agile Hitch is recommended. Sterling TRC is recommended for 9.5mm rope.
4. Retrieval Cord
Utility cord is recommended for the creation of the retrieval cord (4 or 5mm is great). A 50′ length is enough to create the retrieval line and the construction of the tethers for each of the JRB Cinches. Consider putting a spare carabiner on the end of the line to assist in pulling it down.
5. Maverick Pole
The Maverick Pole is recommended for use in advancing the JRB Cinch. It can be purchased at Ape Canyon Outfitters. See dedicated page:
