Pella sliding screen door part
Hello,
Your photo reminds me of our 84-105 Pella roller. Carefully compare the dimensions once you're able to remove your part to confirm that it's a match. Thank you!
These rollers are only held in with screws. The hard part is removing the door from the frame. According to a past customer that was having similar issues, there are four screws that hold the top rail in place, with the ends also holding a plastic bumper. Take out all four screws, and you can carefully remove the top track, slide it off, and replace your stripped 84-105.
I also need a small brown handle for my Pella sliding door with screen inside panes. Can you supply that part? Photo attached
Unfortunately, we do not carry a suitable replacement for the handle in your photo but your roller does look like a match to the 84-105 we've recommended.
