Window balance

Hello there. This looks like our S770-21 Tilt Window Channel Balance. For a stamp option, choose 21B. If your old pivot shoes that the balances attach to are undamaged you should be able to reuse them; otherwise, see if our 15-129 matches what you have. You'll need to make sure the width and thickness match your old shoe. Let me know if you have any further questions.
