BetterBilt easy tilt window balance parts

A handy person from Visalia Ca says:
I need to make sure I order the correct series 190 coil balance. I used your measurement formula and believe I need (2) 6 lb. coil balances, S190-640, can you recheck my calculations? My window is 21" wide by 24" high, it is a double pane window. I have attached a photo of the window and of the parts I removed. I believe I will also need the following parts to repair my window: (2) 15-180, Coil Balance shoe, (2) 15-186, Coil Balance clip, (2) 15-182, Bush Balance.

Again thank you for your assistance,

Paul

Thanks for posting. I recommend weighing your sash to confirm what strength Series 190 you need. That is the most accurate and surefire way.

Thanks, I just did and it is 12.2 lbs.

Great! Assuming you are only using two springs (one on each side), then the S190-640 would be a great choice.
A handy person from Visalia says:
Thanks, I will order the parts. Also what is the best way to lubricate/maintain the Windows.

Awesome, thank you for the order. For lubrication, we recommend a silicone spray.
