nylon roller mechanism for old sliding screen patio door.

Hello there. This looks a lot like our 84-095 to me. Compare the dimensions below to your old roller just to confirm it matches up. Let me know what you find.

I don't believe the 84-028 will work for you, no. The design is very different from what you show in your photos and I can't really see how it would install the same way. Assuming that the 84-095 that I mentioned above is a match, too, then there is also a big difference in size in addition to the design issues.

Then again, I've never tried it. It could be I'm wrong on this, but I am not at all optimistic. If you want, you can see our return policy here.
