Thanks for reaching out! To determine if there is a replacement knob we can offer or another solution, I'll need to see a photo of the hardware you are looking to replace.

Are you able to provide a photo?

Thanks for your photo. It looks like you'll need to replace the key cylinder for your storm door handle set.

I believe you may be able to replace your with either our 40-123 or our 40-129 . To confirm, you'll need to remove your key cylinder from the door and compare the measurements. Let me know if either of these are not a match. We may need to look at other possible replacement solutions.

Here are the dimensions from part 40-123 .
