Window balance replacement

Hello Howard, and thank you for your post. Please take a look at our Series 395 channel balance. This comes complete with  a 19-005 balance top and 15-001 bottom balance shoe. You will need to compare your nylon fittings with ours to confirm this is a match. You will also need to measure the metal length of the balance. It should measure 29", excluding the nylon fittings. If so, then you can go with our S395-29 with a 2830 option that supports a sash weight of 16-23 pounds.
