What gear is needed to tension a 75-120ft line? The best option I have seen so far is the slackline brothers pulleys, but they are expensive. I have also heard of using chain links. Could someone point me towards a reliable source or diagram for the gear I need? college budget would be nice too.

the chain links are great if you dont want knots in your system, I personally use some extra rap rings I have in place of the chain links on my systems. Ill see if I can dig up some pictures for you.

I am also interested in setting up a highline around 55ft long. Would I use the same tensioning system as the setup for a 100ft line, or is there an easier setup available for a shorter line like this?

If you have to ask that then you are way in over your head. You should not high line. You know you fall onto tje line rite? Way more force than walking. Webbing does break at a certain point.

I could be wrong, but I'm pretty sure most people use a climbing rope taped underneath the slackline webbing and anchored as an added safety measure in case the webbing were to break...just a thought. Good luck.

Take all of the aluminum out of your system too. A highline should be nothing but steel.

Some pulling power i've seen used is a come along... check out harbor freight tools for a good price.

I didn't plan on setting up a highline anytime soon. I was just wondering what gear is needed, so when I get to that point in the future, I will have bought the correct gear. Thank you to everyone who has left some advise on here. I have actually found some great systems on slackline.com

when i set up my highline other than getting the line across the drop i didnt tighten it any other way (system wise) than i did my slacklines. what we did to get it as tight as possible was we fed the line through our system (2:3 through some locking bieners and going back through under the line so it auto locked) we tied truckers hitches or overhand on bites into the tail end of the line then had two of us clip in and pretty much walk off the cliff lol... we had to put our legs on the ledg and use them to push... then we moved up... made two more knots cliped and repeated :) we eventually got 3 guys doin it but it got a little crouded on the edge of a precipous :) ..... so theres my two sense

I found all of the information I needed on the slackline.com forum thanks for your help. :)
