Hi, I need to replace a few parts for a window that's not staying up when lifted. It seems that the coil balance fell through the support or something...

Based on the pics, I think I'll be getting:
- 15-191 pivot shoes (2)
- S160-9 coil balance (2)

I also need to confirm the support... should I just get 15-150S? What do you think based on pic?

Thanks! -Andrew

Hey Andrew. I agree the pivot shoe looks like the 15-191. Note that while the Series 160 is often used with the 15-191, so is the Series 165. The Series 160 springs are 1/2" thick, whereas the Series 165 are 3/8" thick. Be sure to measure the thickness of the coil tape to confirm which you need. To know what spring weight to select, look for a stamp on the coil tape that confirms the spring weight needed; or, if there is no clear stamp, weigh the window sash. Give me that exact weight and I can work it out for you. 

If you know for sure you need the S160-9, and just one spring per side of the sash, then yes, the 15-150S will work nicely as a cover. Let me know if you have further questions.

Awesome, thanks!

Yes it's 1/2" (just measured) thick... and the stamp is 9.0 35"

I guess I should be all set then?
