With a Line Locker, it is possible to set up a slackline with no knots. Furthermore it will be perfectly flat with no twisting whatsoever. This method is just as easy to do as tying a knot (if not easier) and comes undone with little to no effort when you’re ready to take down your line. It consists of no more than a single link from a high strength chain. The material should be approximately 5000 pound working load high strength 3/8” chain. You can find this at any hardware store in most cities. Buy 1 foot of the chain and either cut every other link with a hack saw or beg the worker at your local hardware store to do it for you. Obviously you have to cut half (every other) of the links to get the other half free. You’ll get about 5-6 Line Lockers per foot of chain. We recommend painting them so they won’t rust. The following is a step by step guide on how to tie a Line Locker:

Step 1: Push a loop of webbing through the Line Locker where you would normally tie your knot.

Step 2a: Bring the loop up and back around and push it through again right on top of itself.

Step 2b: It goes though in the same direction it went through on the first pass. Open the inner loop so it’s easy to clip.

Step 3: Clip a carabiner though both loops.

Step 4: Cinch it tight and you’re ready to go. The loose end of the line should be coming off the bottom so it’s out of the way.

Line Lockers have been pull tested in a slackline setup, and have reached up to 85% of the normal working load of webbing without a knot. For reference, the breaking point of webbing with a clove hitch is less than 60% of the normal working load of the webbing without a knot. The Line Locker is easier, safer, and a good choice for your slacklining needs.

    I believe my 15 year old son and I will dig this sport. We’ll blend it into our camping and mountain biking for sure. We would love to relocate to Boulder Colorado or anywhere cool out west, in time for sure.

    Love you site, thanks
