The hanger can be used both to swing and to swivel. Able to swing as well as pivot, they are perfect for hanging things such as the sky chairs. Just using one & holds 200lbs no prob. This bracket is plenty and does the trick!
It works perfectly and is very robust. Stainless material seems really solid and should last years to come.
This is a horrible design, and it's totally unacceptable for something that is rated at 1200 lbs to fail in this way. Holes are too small and two different sizes. Impossible to install.
But it’s doable if you don’t mind those.
