I have an extension spring garage door that doesn't open and close smoothly, and many times it doesn't complete a cycle before jamming up. I recently discovered why - the stationary pulley is quite literally eating the piece it's mounted to.
Full imgur album here: https://imgur.com/a/C2qRsRG (First two images are closeups of the pulley that's eating its mounting piece and second is a wider shot of the matching piece on the other side)
I can't figure out what the piece the pulley mounts to is called. It's not the flag bracket, that's the vertical piece bolted to the wall that supports the pulley piece and the vertical track, and it's not part of the horizontal track either.
As an alternative to this exact part, since it may not exist, could I replace it with a piece of C-channel, unistrut, or even that right-angle hole punched stuff that holds up the opener and track ends?
As for make and model, I know the door is an old Raynor model but I haven't been able to find any information on something that old, and Raynor is more interested in selling me a new door than providing support for their old stuff.
