My top and bottom sashes won't stay up or tilt

A home owner from Gloversville, New York says:
My top and bottom ashes won't stay up and fall out when I tilt in to clean. They are both missing the silver piece I'm pointing to in the last picture

I meant sashes. I need the little pin part that I'm pointing to. It's about an inch long and fits in the bottom of the sash. The pin locks into the round part. I'm not sure how else to explain it

Hello,

I suspect that you may be looking for our 26-423 pivot bar but you'll need to remove the original part to confirm that the specifications match up with yours. Thanks for posting!
