I'm constructing an EMT pipe tarp canopy frame. It will be a shed roof. One side will be pipe supported (low end) and the other side (high end) will be mounted to the top of my garage roof.
The plan for the garage-side was to use foot plates that have an adjustable angle on them so that they can be mounted flat on top of the roof, then have the pipe fitting adjusted vertically.
It would look like this:
...except that the connection between the plate and the pipe fitting would be an adjustable angle.
I have seen this before but have no idea what it's called so I can find them online to purchase.
Does anyone know what these are called?
