HOWTO: setup a slackline using the 4 carabiner "primitive" method

This shows you how to setup a slackline using two loops slings (tied with water knots in this case), 4 carabiners, 2 forged rappel rings for line-lockers, and 60 feet of webbing. For videos on how to make the slings or use a line-locker, see nwslackline.org

What is the maximum range for a setup like this one in the video?

[Adam Burtle]

Up to 80 is comfortable. Perhaps around 100 is the max I would consider. Even at 80 feet you will need 3-4 people to pull it tight, and the tension+friction will be enough to rapidly wear the portion of webbing inside the friction lock (it will start to heat weld).  I have rigged 80-100ft primitives many many times, but it does wear the webbing a bit faster.

Is this easier to pull slack than using 2 biners with a friction knot? it seems like this way has more of a mechanical advantage?

[Adam Burtle]

I have tested all varieties of this sort of setup (3 carabiners, 2 carabiner, 4 carabiners, etc) and this is the most efficient according to my dynomometer.

Is it ok to use aluminum carabiners or should I use steel? Thanks

I bet the only limit there is carabineer size. That being said, my setup has one where this one has the double. This makes mine look like I am working too hard. Off to buy one more. :)

Does anyone know if this same system could work with 50mm(2 inch) webbing instead of the 25mm(1 inch webbing) shown here?

...?

How much webbing was used in the slings that where water knotted

[MrHawtyman]

I bought a ratcheted slackline before and it has broken. I am looking for an alternative method for setting up one. My only concern with this is if it can get as tight as a ratcheted one can, or if it can get tighter?

A girth hitch or choker configuration actually makes the sling weaker- for short lines like this triloading isn't something to worry about unless you are bringing your lines up to crazy tension for tricks.. and then you can always fix it by using a basket configuration (see Adam's video on slings).. of course you can do what ever you want- these are just my preferences

Is this as easy to take down as it is to put up?
