Window balances

Question

Need to replace both balances for my window.  The old balances have the following code printed on the balance "29 3 CX CMC 7".   Any help would be appreciated

Thanks for your photos. Based on what I see here, you have either our S380-30 or S385-30, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.
