Loop Runners and Light-Duty Slings
Loop runners are sewn webbing loops that do a dozen small jobs: a quick anchor around a limb, a choke for a light pruning line, a tool hang point, or a short extension in a climbing system when it's rated for that. They're cheap, light and always worth having a few on the saddle.

Buying guide
Choosing loop runners
Runners come in lengths from about 2 ft to 6 ft or more and in nylon or polyester webbing. Nylon stretches a little more and handles shock better; polyester holds up better to UV and stays stiffer when wet. Pick a few lengths so you can basket or choke limbs of different sizes without tying knots in webbing.
Check the rating sewn on the label and keep light-duty slings to light-duty work. For removal rigging and anything that will see dynamic loads, step up to heavy-duty rope slings sized to your rigging line and block.
Care and retirement
Webbing is easy to cut, so keep it away from saw chains and sharp bark edges, and use a sleeve where it wraps a rough stub. Retire any runner with cut or fuzzed edges, glazing from heat, chemical stains or damaged stitching.
Store runners out of the sun and away from fuel. If a runner is used for life support, it must carry the right certification and be inspected like the rest of your climbing system.
Common questions
Can I use a loop runner as a climbing anchor?
Only if it is rated and certified for life support and used the way its maker allows. Many light-duty runners are meant for rigging small pieces and tool hanging, not for climbing.
