I had taken out the broken balance. The above part number is stamped on it. Please advise which pair to order from you.
I had ordered before from you, with excellent service.
Best wishes, Karol

Hello,

If your bottom attachment measures 1-3/32: deep, I agree that the S385-28 channel balance would be the correct replacement. Based on the stamp shown on your original balance, you'll also need a 2750 strength option for your replacement balances. Thank you!
