Of course, the easiest way how to build a slackline is between two trees – but what if there aren't any on your garden? Or if you want to install your line on a beach or even indoors? Don't worry, there are many techniques for rigging a slackline without trees:

Outdoor

Something similar to a tree For: urban areas Needed: nothing (line protection sometimes) The simplest alternative – use poles (telephone, volleyball etc.), posts, pylons, railing, large street signs and others. Warning: Use only solid and securely anchored stuff and always test it first. If it can be shaken, moves a little while walking on the line, or if you are not 100% sure they are strong enough, find a different place. The line is able to create enormous forces, which can easily destroy weaker anchors (just take a look at the video below or a forum thread here).

Permanent deadman anchor For: garden (or other area that belongs to you) Needed: shovel, 2 solid anchors, chains, 2 shackles (or carabiners), 2 A-frames Ideal solution for your garden if there aren't any trees. The system is the same as the Temporary DMA, however use stronger anchors (for example a metal tube sealed in concrete) and instead of the line, attach a chain (normal, from any hardware store) to them. Also, on the other end of the chain (when it leaves the ground), use a shackle for attaching the line (see the first video for tutorial).

Auger anchors, Duckbill earth anchors For: soil or sandy soil (not so good in pure sand) Needed: 2 or 4 anchors, 2 shackles (or carabiners), slings, 2 A-frames Using auger or Duckbill earth anchors is slighty more expensive but also a lot easier compared to the deadman method. Auger – these are cheaper and also easier to get out of the ground. You can get them here. Duckbill – available here. Slightly more expensive as you would also need the drive steel tool to hammer them into the ground. They are easier to get into (see the video below) but to get them out of the ground, you would have to dig them out.

Watch this video on YouTube We would rather recommend you to use a pair of these anchors on each side, just to be sure. Then make a connection point using shackles and some climbing slings for example, and finally add two A-frames to lift the line to desired height.

Temporary deadman anchor For: beach, heavy snow (easy to dig spots) Needed: shovel, 2 anchors, 2 A-frames Great for slackline session on the beach or in a heavy snow. Dig a hole 3-4 feet deep, attach your line to an anchor (a log or short plank for example) and bury it in there. Then repeat on the other side and add two A-frames, plywood boxes or similar things to hold the line in the right height. Of course, the main disadvantage is that you have to dig those holes again to retrieve the line – which makes this method quite time consuming. So if you are on your own property, use rather the permanent method.

Build your own posts For: garden, beach etc. (places where you are permitted to install it) Needed: digging tool, 2 rounded wooden posts (at least 8 inches in diameter and 8 feet long), concrete mix, water, spade, wheelbarrow or trough You can even build your own posts. Dig two holes at least 5 feet deep and about twice as broad as the posts. Install the posts there, prepare concrete (watch the video below) and fill the holes with it (make sure the post is in the center of the hole). Wait at least two days until the concrete becomes perfectly firm and you are ready. And when anchoring the line, wrap it several times around the post to prevent it from slipping (see the picture above). Show Video Show Video Hide Video Hide Video How to Mix Concrete by Hand

Use your car

For: almost any place Needed: vehicle (log, A-frames) Warning: Never use your car to actually tighten the line, you can damage it easily. Also, use this setup only for walking a short line, not for activities that involve higher forces or more tension (longer line, jumps, bounces). There are several possibilities how to use a vehicle for slackline setup – you can anchor it to the towing shackle / ball, or you can try the wheel and log method: Get a loop of line under the wheel (driving over it or using a car jack) and anchor it to a small piece of wood (2-4 inches on diameter is enough). Then use A-frames, plywood boxes or similar stuff to raise the line to a desired height.

Indoor

You'll probably spend most of your slackline sessions outdoors, in the nature – however, there are situations when you'll appreciate an indoor setup. For example when it's raining (on the other hand, a lot of people love slacklining in the rain ;) ), in the winter or even in your office for short relaxation pauses.

Visit your local gym / climbing center For: tricks training for example Needed: nothing The most obvious choice is to check your local climbing gym – many of them offer whole areas dedicated for slacklining, or at least a possibility to rig a line there (small poles like this from slacktivity.nl are often used). Of course, it's not as pleasant as slacklining in the nature – but great for learning new tricks because you can always get enough protective mats there (see the video below).

Expansion bolts For: your home, office, garage, basement Needed: 2 5/8" expansion bolts (each with 2 washers), drill, 5/8" drill bit, wrench, something for cleaning the holes + 2 A-frames (or boxes, milk crates etc.) You wouldn't probably use this method outdoors as there exist many easier setup techniques – however, installing bolts is one of the simplest ways how to build a line in your flat, garage or even office.

How to build A-frames for slackline

Needed: wood, screws, bolts, saw, drill

There are several manufacturers who produce A-frames dedicated to slacklining, however the price is quite high so we would rather recommend you to build your own frames. Don't worry – It's easier than it looks and you need just a few tools and some wood.

Here you can see a standard A-frame, 4×4 feet large, two slightly different designs (click on the picture to see full size).

Typically, two or three bolts are used to enable setting the line at different heights. Make sure there is enough space if you use the wider 2 inch webbing.

You can also add a supporting board to the lower part to make the frame even more firm.

You can find the list of needed wooden pieces with their dimensions here (go to Step 7).

You can also see a step-by-step guide in the following videos. However, chances are you probably don’t have all those tools, so use it rather as an inspiration or reference point:
