What kind of carabiners should i use to rig a slack line?

Question

i see many different shaped carabiners and dont know which is the strongest or most ideal for rigging.

also which riging system requires the least amount of people?

Answer 1

The best carabiner shape for any kind of static rigging is a symmetric shape - oval is the best. Most carabiners are asymmetric "D" - which is stronger but will cause the line to shift when loaded - the oval shape is better because nothing will shift to one side of the carabiner when loaded.

You could use standard aluminum carabiners or even locking ovals (Petzl and Omega make very nice locking ovals), but I would also suggest using steel carabiners - they are cheaper and stronger and since weight isn't an issue they are better.

Answer 2

It's recommended that you won't use the climbing equipment to slack line, it's being constantly under force so it might deteriorate and break on the climb. I use cheap steel carabiners, oval-shaped and with a safety.

Regarding of what Sky said, that carpet helps protect the bark of the trees, if you harm the bark the tree might die.

Answer 3

I can rig my slackline with me, myself, and I

and I'm not very big.. lol

I use 5 carabiners, basically my cast-offs from climbing. They're just basic locking carabiners..
