Window can't be removed; how do I replace balance?

Thanks for contacting us, Frank. This is a good question, and a tricky problem.

First, I recommend that you look at our 75-005 Spiral Balance Charging Tool for Non-tilt Windows. With this tool, you can hook onto the old balance from the bottom then and then detach it from the shoe. Next, you will want to unscrew the balance at the top and pull it out from the bottom while someone else holds up the sash.

To install the new balance, slide it up behind the sash and between the shoe. You will once again want someone to hold up the sash as you do this. Screw in the top of the balance and finish up by charging it with our 75-005 tool.
