Basal Anchors for SRS

In Stationary Rope Sytsems (SRS) / Single Rope Technique (SRT), the climb line is often anchored at the base of the tree, and then run over the the Primary Suspension Point (PSP) in the tree and back down to provide the single leg of rope upon which the climber ascends. This means that the force on the PSP will be double the force exerted by the climber. SRT systems have the advantage that there is no need to isolate the rope.

A basal anchor sling made from rope offers a nice anchor point for your SRS system, as it is quickly adjustable to cover a wide range of trees, and gives you options for attaching a figure eight, Petzl Rig, I'D, or other belay device which can be used to lower off the climber if needed.

CMI Anchor 15’ Sling

15’ Anchor Sling by CMI

cli512

CMI Anchor Sling is a simple, versatile, and adjustable sling that you can trust. Made from heavy duty nylon webbing with stitched pockets for an easy and safe connection. Created by a climber for climbers. Original design by Gerry Garcia.

Basal Anchor Sling - Wrap the sling around the base of the tree in a choking configuration with the webbing going through the stainless steel ring, avoiding fiber on fiber contact for longevity. Always clip a ring on the first available pocket to keep a snug connection. Once clipped in, choose a pocket to clip in your climb line. Always be sure to clip into 1 pocket, not 2. The options are endless with this sling; connect straight with a carabiner, or add your favorite lowering device for an easier rescue in the event it's needed.

Pocket Strength: 2,000lb • Overall Strength: 10,000lb • Stainless Steel Ring rated: 10,000lb.

The Bugg Base basal anchor was developed by Colin Bugg, competition climber and PNW 2012 Champion. It is a very simple basal anchor sling that deploys quickly and comes off the tree very fast. It has two DMM shadow carabiners which allow smooth passage through the large 10,000 lb stainless steel ring. The carabiners on the Bugg Base are set up in line to facilitate using a Petzl Rig or I'd and allow for a back up tie off. The rope sling is made from 7/16" Sterling HTP rope for excellent durability.

ART (Advanced Ropeclimbing Technology) has created the Snakeanchor to serve as an adjustable anchor which can be used as an upper anchor (false crotch or friction saver) or a lower anchor for your SRT climbing. The Snakeanchor is made from doubled cord which is stitched together with openings every 2.7 inch so that a carabiner can be inserted at any point along the length, making it adjustable based on which point you use. ART has used doubled 8mm cord to give the Snakeanchor a wider surface area for better grip and abrasion resistance. An aluminum ring protects the eye at one end. WLL on the Snakeanchor is 2 kN. Available in 8' or 16' lengths.
