The top rollers were clearly broken - cheap plastic that had degraded severly with the Florida heat - part of one of them even fell out of the door as I was taking it down. Problem is, I only have part of the roller assembly (the part that fell out), and couldn't figure out how to get the remaining part of the assembly out of the door so I could get a replacement assembly. Looking at the different sites that sell replacement parts for sliding screen doors, since I don't know what the remaining part of the roller assembly looks like (the part that's still in the door frame), I can't figure out which replacement part to buy.
Is there a generic (one type fits all) top roller assembly that I can use? The top roller assembly in this type of door is only there to guide the door in the top track as it slides back and forth - it doesn't need to bear any weight.
