Want to setup your slackline, but you don't have a couple of big trees (conveniently spaced apart) located nearby? No problem! Here are a few options for rigging up a slackline without anchoring your line with a tree.
Option #1 - Use a Kit: You don't need trees to slackline. You just need a couple of anchor points, and something to suspend the line off the ground. Enter the slackline stands & anchors kit. The basic premise of all the kits is the same, with the main differences being in price, flexibility and anchor points.
Slackabout Kit - A simple "a-frame & anchor" kit that isn't highly technical, but is affordable & highly portable. Simply drive the ground nails and set up the simple wood a-frames underneath.
A convenient height for most people. The biggest drawback is it can take some muscle to drive the nails into hard ground.
Freedom Kit - A more feature rich/complex slackline a-frame kit that uses ground spikes instead of augers. The ground spikes will hold heavier loads than an auger, but are only really necessary if you're planning on doing tricks on the line. The wood a-frames have multiple different height settings.
No-Tree Slackline Anchor Kit - A heavy duty and highly adjustable a-frame kit. This is like the Ferrari of slackline kits.
A hefty anchoring system that you know won't pull out of the ground, as well as metal a-frames with many different adjustment levels. This kit really only makes sense for the most serious slackliners, both because of the price ($415) and because the adjustable frames and bulky anchors are way more than most people need.
Gibbon Independence Kit - A highly "polished" slackline a-frame and auger kit with multiple different height settings. This kit also happens to come with a slackline, if you don't have one already. What's nice about these is the multiple height settings ... the lowest settings are nice for little kids.
Option #2 - Get Creative: We've seen all sorts of creative ways to setup a slackline ... some brilliant, some with unfortunate (but hilarious) results. In urban areas, the best alternatives seem to be telephone poles, cemented street signs, and bolted down park benches. If you're outside the city, truck hitches and big boulders are popular anchor points off the ground.
The key takeaway when looking for an anchor point is to never anchor on a load-bearing support, especially at your house. The torque of a ratcheted down slackline is greater than you think!
For example, see this gentleman, who used the brick pillars outside a grocery store.
If you have a space (in your backyard or otherwise) where you plan to slackline regularly, you might consider setting up some permanent anchor points.
On option is to setup a permanent deadman anchor (and make your own a-frames).
Another permanent outdoor option is to actually install slackline-specific wall anchors (usually in concrete walls). You can find complete kits online for installing these outdoor anchor points.
The more we research indoor slacklining setups, the more we realized ... people are clever. People have come up with a number of innovative indoor slackline setups. Here are a few.
The one you buy: Gibbon Slackrack 300 - This is a completely self supporting system that can be setup inside and keeps the slackliner only a couple inches off the ground.
A great option for slacklining inside, or for kids just learning (because it's so close to the ground). The major drawback of the Slackrack is the cost ($1,000!!), as well as it's length (only 10ft).
Boards & Doorframes: This is one of the more clever setups we've seen: using a 2'x4' as a deadman anchor behind a doorframe.
Floor Bolts & Chairs: This guy went above and beyond to install a "permanent" indoor setup by actually putting big bolts in the floor. We love the use of chairs as "stands".
Concrete Wall Anchors: If you have a bigger indoor space with solid walls you could look at installing permanent concrete wall anchors.
