re: Shower door bumping in top corner. How to level?

I adjust mine all the time. That heavy glass slides in the rubber gasket.

Make sure to support the door (I recommend an air bag pump shim thing like I’ll link below). Have it a little open or closed so when it’s loosened it doesn’t lean on the fixed panel.

Loosen the top screws on one side of the hinge just enough so the door becomes movable.

Pump shim up until door has an equal gap top to bottom

Tighten screws as reasonably tight as you can without stripping them

Release air from shim and remove.

With a 9’ door I would have someone standing there just holding the handle of the door to not let it move. If it was a shorter door you could have one hand on the handle and use the other to do the screw work but you’ll have to be on a ladder for 9’.
