Hey, Mike. It definitely sounds like you should consider new balances. Over the years, time and consistent use puts a strain on the springs and pulleys, making them harder to operator. Lubricating them was a good idea, but since that didn't yield any results your next best option is to replace t hem entirely.
As for the handles, we carry a couple different kinds that just screw right to the face of the sash. See our 26-116 and 26-174, along with a screw like our 33-080. When drilling holes, it's vital to make sure you don't hit the glass. |
