Corner of Old Storm Windows and Screens.

Thanks for posting. I would recommend that you consider our 91-010 and 91-011 latches (which use the 91-102 spring). They aren't exact, but they may work. For the corners, take a look at our 95-008, 95-009 and 95-233. I have repaired storm window inserts like yours before with the plastic corners and I find they're pretty close to the original. I'm just not sure of the bottom corner that attaches to the handle section. Compare the parts to yours and see if they line up with yours.
