I'm going to try to bend a tilta-door (for the garage) straight again. I am considering pulling it off first.
In order for me to do this I have one obstacle and it's this one connector that looks like a rivet. It has a rounded head on one side and it looks like it's been riveted onto a washer on the side of the photo. Any clues how I can get this off - or is this a one use thing that needs to be cut off?
