Need two new channel balances and parts - 34D

Question

My channel balances are marked with 34D and look to match your product #5770-34. They screw in with one screw at the top. The shoes are also broken. I have included a photo from a non-broken one that's still in the channel as I am going to have to cut the channels to replace and didn't want to do that on a working window. The channel balance is 9/16" and 34" long and as I said marked with 34D. The shoe shown (#15-129) with that balance appears to be the right size also, but my pivot bar is different from the one shown with it. Can I use the pivot bar 26-021 with that shoe? Or do I need something else? I have included a photo with a ruler of the pivot bar showing the length and screw hole and it looks like they would line up, just not sure if the end of the bar would fit in the 15-129 shoe. Let me know your thoughts.

Thanks, Karen

Thanks for posting, Karen. Good work on all this. I agree, this appears to be an S770-34 Channel Balance with a stamp option of 34D. The shoe may well be our 15-129, but I'd still remove it to confirm the width and thickness to be safe. Your old pivot bar appears to be our 26-040--this bar works with the 15-129, so you shouldn't have any issues. Let me know if you have any other questions.
