Screen knife latch

Question

Home is about 15 yo.  Bought it last year from original owner.  Not sure of window brand name.  In side window sticker states Doyle Lumber.  The current latches are plastic and very brittle.  Looking to replace approximately 100  plus.  I have attached three photos of existing latches.  Thank you for your help!

Hello,

I can't be sure but it looks like you may have a damaged version of the knife latch shown in another customers post here. If so, take a look at the 70-172 latch pair that our senior expert mentioned to see if they might work for your application. We can't make any guarantees but review the specifications below and see what you think. Thanks for posting!
