window balance id needed

A handy person from Florida says:
I have two balances that need replacing. They are stamped "233".

They are 1/2" chanel and 24" long

After looking at your premade balances It looks like they have a 19-002 top and either a 15-001 or 15-002 shoe.

I can't seem to see any difference between the two. My shoe looks similar but just a little different.

Can you help me with this?

Thank you,

Thank you for posting, Don! It looks like you have the 15-001 shoe. In that case, take a look at our S390-24 with stamp option 2330.
