Needing all hardware for storm windows. There are no numbers on any of the parts although I feel like the latch is similar to your part 91-050.

The 91-050 is very similar, but I cannot confirm if it will work or not. You will need to carefully compare your dimensions to ours to confirm that they're the same size.

The same goes for the corners, it will ultimately depend on dimensions. I need you to measure yours as carefully as you can and tell me what you get. In the meantime, you can see our entire selection of corner keys here.
