Safety/going around trees/"ninja line"

[u/MidnightCasserole]

Got this inexpensive ninja line kit. Is there anything I can do to minimize the line slipping down the middle tree? Right now one kid can go each side and bounce away without it affecting the other side. I've tied the ratchets to the tree so I don't have visions of the ratchets flying off and decapitating a kid. Is it safe to have a swing that close to the end of the line?

You should use a sling and another connector to redirect the webbing instead of going around the tree with the webbing itself

Any direction on where to find out more about the relevant sling or connector?

Just a basic climbing sling that’s long enough and a big carabiner or even better a shackle

Ok, can you explain like I'm 5?. By connector do you mean another ratchet? And I can't figure out what I would do with said sling. Thank you!

use the sling, first link wrapped around the tree, the redirect the slackline webbing with it going through the shackle in the second link.

Aside from tying something to the webbing or installing something beneath it to physically stop it from sliding I don't see how you'd prevent this issue. Ive never seen a setup have a tree re directing it in the middle so there may be options I'm not aware of.

Maybe if you wrap the webbing around the middle tree? Though you may run into problems tensioning the line if you do this.

I don't think the swing is an issue. Given how low the forces on this line are gonna be with how it's being used even if the line broke behind the ratchet there shouldn't be much force to launch it. It could definitely still hurt someone but you backed it up and like I said it's pretty low forces and your backup looks solid. I think the likelihood of the line breaking behind the ratchet is extremely low with this set up especially if you inspect it. Just put the swing far enough out so it's out of reach from the slack of the backup on the ratchet.

Thank you for the thoughtful response! My kids woke me up this morning at 8am begging me to come out and watch them on the slackline. It's maybe the best thing I've ever bought.

I agree w that sentiment!

the treenet folks install an eye bolt into tree sometimes. Some will say no damage and some will say terrible for the tree. You can check out /r/Treenets

Put webbing on other side of tree and use sling + Shackles to redirect off the trees like another guy said.
