Trying to find a replacement for this part.  It goes inside the side frame of the window. Screwed into frame at top, cord attached to a shoe that the pivot bar sits in. Only marking is the number on the back

Hey there!

Thanks for reaching out to us. The Series 770 looks like it'd be a match. The 1600 stamp is odd, though, and doesn't translate to our stamp options. With that said, you'll have to weigh the window sash on a scale and refer to the weigh chart under the product description on the S770-16 store page.

Let me know if you have any questions!
