Storm and Screen repair parts

A handy person from Youngstown OH says:
I'm looking to repair a number of screen and storm inserts. Mostly the corner/latch parts are broken, but some of the top corners are also broken. It appears your parts 91-005 and 91-004 will work for the latch/corners and part 95-004 will work for the top corners. Do you agree? I take it the spring mechanism eliminates the need to crimp. Do you agree?

Pics of the RH latch/corner and top corner (front and back) are attached along with the the assembled corners in an insert needing replacement glass. The latch corner is stamped with the number 7003 and the top corner has the number 10 on one leg and 23 on the other. These were purchased from Three Rivers Aluminum Co (Traco) of Pittsburgh, PA in 1978. I assume I'll have to drill out the crimps in order to tap the corners out of the frame?

Good morning! Thanks for posting. It looks like you have an older corner latch that is no longer available. That said, we use our 91-005 & 91-004 corner latches as replacements. The only difference is that these newer models are self locking, and you don't have to punch the corners. For the plain corner key, I agree that you would use our 95-004 self locking corner.
