Hey, Sam. Your windows may be hard to move up and down because the springs are either shot or were never the correct strength to begin with. Are all the windows the same? How about the stamps on the balances? Are they the same as well? The stamp is what tells us what the strength of the spring is.
You may want to weigh the window sashes and let us know what their weights are. We should also know the stamps printed on the channel balances installed in those windows. With that information, we can tell you if the springs are the appropriate strength. If you want to stick to the same strength balance as the one you sent us a picture of, you need to order S395-28 with the 2730 option. |
