Do you carry these screen door wheel adjusters?

I swear I've seen this part before, but I can't find anything similar to it for the life of me. It must have been an old part I came across years ago. I'll need a little more help before I can say for sure if we carry this. First, do you know who made the door? Knowing the manufacturer may offer us a clue. Can you also show me what the wheel itself looks like?

Hopefully that will help jog my memory. Thanks in advance!
