This company manufactures a really neat bracket for quickly building obstacles. While we don’t own any of these brackets (and are NOT being paid to write this post) we think it is a super neat idea because it allows flexibility so you can easily change things up. Even if you aren’t buying the brackets, this video has LOTS of neat ideas for obstacles so it is definitely worth checking out.
Note: We did search for but were unable to locate the website that actually sells the brackets. Any of these obstacles could be built without them as permanent/semi-permanent obstacles.
