Question 1

Accepted Answer

Yes!!!
I’ve used them on our deck for a few years!
They are sturdy!

Question 2

can these be used with heavy blackout drapes?

Accepted Answer

I used them on heavy drapery fabric that was also lined with heavy blackout material.
Just be sure your circle cut out is big enough to expose the threads on the grommet.

Question 3

Do these work with the Rowley grommet tape?

Accepted Answer

I did not use any tape.as my fabric did not need any extra support and I wanted to space my grommets myself. 
I think you could if the hole in tape was proper size
