Can I see a few pictures of the knife latch in question? I could not use that patent number to find it. Thank you!

Please see a picture of the attached knife latch for my screens. I need 2 left and 2 right latches.
Thanks,

Thanks! Take a look at our 70-172 and 70-174 and see if either of these pairs could work for you. Make sure to carefully compare dimensions to your own hardware.
