    Terrible experience. Company shipped order to wrong address. Items would have arrived late anyway. Not worth the cost. Easy connectors for conduit can be made with a cheap angle grinder and drill. The cheapest welder makes far superior connectors. Making your own connectors adds maybe 3 hours to a build. This greedy company wants to do direct sales only which makes you wait days (if they show up at all). Definitely not worth the high price or the cost of adding uncertainty to your project. Stay away.

    TinkTube is an excellent product for rapidly prototyping your ideas into strong, attractive structures.
    I love that you can build almost anything using just a tape measure, marker, pipe cutter and one T wrench!
    And it is quick and easy to modify and adapt rapidly when you need to mount a new projector quickly, as I did one night.
    Ordering is easy and delivery fast, and TinkTube will even help you on your first design with hands on help from Estaban as he did for me
    for my first projector cage mount. I highly recommend TinkTube for anyone who likes to design and build your own structures.

    This one works really well.

    It would also be great if there was a similar set like this that has just a little bit of a wider gap or an adjustable gap.
