RCI Set ups: Group Abseil

The group abseil is one of the more complex set ups shown on the RCI training. Sometimes this leads to confusion with some element of the set up.

Below are basic step by step instructions that RCI trainees might find useful. This blog is designed to jog your memory rather than teach this set up from scratch, so if you are not experienced in the skills required to build this set up, please don’t attempt it without additional guidance.

Anchors

Every crag top is unique, but working on the assumption that you are placing gear for your anchors, you will need a minimum of 3 anchor points for a group abseil. There will always be exceptions, but for the purposes of this lets work off 3 placed anchors.

Three Loops

Working off three anchors, its quite easy to have 3 loops coming out of your large fig 8 knot (BFK). The common mistake I see made here is that the last strand of rope isn’t included in the BFK when its tied, which can be extremely dangerous as it just pulls through the BFK when weighted.

See the pictures below. If the last strand of rope isn’t coming out of the back of the BFK then its not tied properly.

Cows Tail, Saftey rope, Abseil Rope


If we’re aiming to deliberately create 3 loops, logic would suggest we must have a use for each loop.

  • For your safety, connect your harness to an outside loop by a cows tail and crab or purpose designed lanyard.
  • connect the dynamic safety rope to the middle loop using a tied off Italian hitch.
  • connect a separate static abseil line to last loop via a tied off Italian Hitch, so that it can be completely releasable from the anchor.

Positioning & Final Set up

Take the time to think ahead when setting up. The final picture should be clean, organised and easy to understand what each part is doing in the set up.

  • We shouldn’t have any trip hazards for our clients to navigate around and be set up in a way that they can easily approach.
  • The set up should be an appropriate distance from the edge of the cliff, to allow clients clip in, while still being safe and to allow them time to get used to the process of moving backwards.
  • If we use different coloured carabiners and figure of 8s we can refer to them by colour rather than by use, which makes it easier to instruct our clients when they reach the bottom.

The pictures and instructions above give a good basic example of a safe and tidy set up. While there are many tweaks and adjustments that can be made to improve its use, I have kept the set up as simple as possible.

Once you are comfortable with the basics and have practiced working a group abseil for real, then these tweaks should be obvious to you or indeed feel free to get in touch and we can discuss variations to the set up.

Remember to always dress and stress your knots and leave a long tail and/or tie a stopper knot.
