Window screen parts

I'm afraid that I don't understand, either. If you're looking for replacement springs then I can do my best to help you, but I will need some kind of reference to work off of. Do you have any of the old springs on hand for us to look at? If not from the screen in question, maybe another, identical screen for another window in the house. 

If so, you can upload a photo of it right here for me to review. I can then check our inventory for a potential match.

If not, then I'm no sure that we can help you. If there is no hardware at all on your current screen then it likely won't be possible for us to find a match. We cannot identify something if we can't see it, unfortunately.
