Need latches and corner pieces storm door

Hello, thank you for posting,

Your parts look like the type used on EMCO storm doors. Take a look at the 95-249 corner set used for Larson. I believe this set which has an assortment of different corners should help fix your glass panel. As for the slide latches, I recommend the 91-183 that are used on Daco storm sash. The dimensions are close to the one you need. What I have found is that the height of the 91-183 latch is not as tall as the one EMCO used. If you find that the new latch is loose in the lift rail of the storm sash you can tap up the bottom of the lift rail a little to make the gap not as tall.
