Two part video on replacing W shaped tension roller on sliding screen door. There are various shapes of roller springs; this is just one type. The intro is a very quick slide show for those that just want to see photos and steps, the remaining is video footage of the process.
This is for screen doors with very short slot for spring, and where it’s blocked by a plate from sliding enough to simply pull out.
