Capitol window spring 28 inch long

Thanks for your inquiry. Unfortunately, this is not enough information for us to determine a replacement balance. We would need photos of the balance, along with the metal length measurement of the balance. From there, we will be able to provide some recommendations.

Looks like one of our half-inch non-tilt channel balances, but I can't be sure which, since you haven't removed it. See if one of those balances has the same plastic attachments as yours.

Yes, as I said, this is a half-inch non-tilt channel balance. Click the link above to see our options and pick one.
