Channel balances

Thanks for your photos. Based on what I see here, you have either our S351-29 or S390-29 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.

For an 18 pound sash, I would recommend our 2830 option. This also happens to match your old stamp, so everything looks to be in good shape!
