Looking for replacement screen door rollers. They were spring loaded units that fit between the corner joints and one screw holds the corner and the roller and the other is the adjustment screw. Looks very similar to 84-095 but the measurements are out since the bracket is a little different.

Thanks for posting! It appears that our 84-095 is the closest possible match we have. I would just double check all your measurements. If you still aren't sure, please let me know what the dimensions of your own roller are. Please make sure to include width of the housing and wheel diameter.
