Folks - five years ago, you saved me a couple of hundred bucks by selling me a pivot bar for my ancient vinyl windows. I thanked you again, and repeat: THANKS!!!
Today, I found that one of my Lowes double hung (double pane) vinyl windows was leaking - because the left latch on the bottom (inner) sash was broken. This window was installed (by a contractor) in spring of 2016.
I am showing you pictures of a window with a working latch, hopefully this will give you a better idea of what the part is supposed to look like.
Bob
