This is from the Black Diamond quality control website.
“before you join two slings together think about the following:
- Is it possible to use a longer sling altogether?
- If you need to join to slings, using a carabiner is stronger
And in addition:
- If you must join two slings, use the same materials and width
- Symmetrical knots (like the Strop Bend and Climber’s Hitch) appear to perform better than a standard Girth Hitch when joining two slings together.”
Oh goody, a new type of hitch/knot. Here’s a strop bend, which is basically a girth hitch all dressed up.
