Non-Tilt Window Channel Balance replacements

Thanks for posting, David. Sometimes even using a lubricant won't help the balance operate more smoothly. It may be worth a try, but at the end of the day it's probably best to simply replace them. From your photos, I would recommend our S350-37 with a 3650 option. This comes with the 19-002 and 15-004 bottom pre-attached. Let me know what you think of this recommendation.
