I'm looking for replacement balances for Anderson window. The numbers stamped on the existing balances are J48 519 10-88 as well as 11600-17. I can't find the numbers on your site that would match, so I'm looking for a suitable replacement.

I recommend our 24-531. This can replace Andersen sash balances stamped with 519.
