On a side note for those who want to keep the glass
up temporarily...

Sure you can tape it but with sticky tape, it can be a
nightmare to remove the tape.

It is easier to use a short piece of wood, such as a broom stick.
Just cut a shallow groove so the glass can sit on the groove.
Then zip tie the piece of wood so it does not move around.
