This structure allows you to set up a slackline without using trees, poles, or A-frames. It's very easy to build!

I suggest reading through this Instructable for ideas and then making improvements wherever you see fit. I'm definitely not a pro :)

Step 1: The nuts and bolts

There's not much to it. If you want to copy my design, you'll need:

8'-foot 2x4s (x9)
6" long ½" bolts (x12) with nuts (x12) and washers (x24)
Simpson Strongtie End Post Cap LCE4 (x4)
Simpson Strongtie Tie Plate (x8)
Simpson Strongtie Shelf Bracket CF-R (x2)
Nails for Strongties
3" Wood screws
A hammer, drill, and saw.
Love it thanks
Great idea! <br>Although I would be concerned about being injured on the beam or on the beam's protruding screws...
Yes, the bolts are a bit of a hazard, especially because some of the bolts I selected are an inch too long (7&quot; instead of 6&quot;). This isn't a good setup to learn slacklining, but it's wonderful for people like me who enjoy slacklining but don't have any other way to set it up.
Ha. How did I miss this when you published it? Doesn't beat two trees, but if you don't have two trees, this is great! Didn't know you slacklined lance, love the slow-mo shots! <br> <br>J
Thanks! Glad you liked the slowmo shot - I thought it may have been a little too 'show-off-ish.' I'd rather have two trees also, but alas my yard lacks that. And besides, this way I get to play with power tools and enter the wood contest :)
I think I might adapt this for an indoor hammock stand!
