Coil Balances

Question

Hello,

I cannot find a model number on my windows but these to me look like 150 series correct? I found the number #6 and #7 posted on the coil themselves. I just wanted to see if I am order the right parts below.

#7 (S150-7) coil

pivot shoe (15-140)

cap (15-144)

support barrel (15-145)

#6 (S150-6)

Thanks

Tib

Hello,

I agree that your coil balance assembly resembles the 15-140 balance shoe, which uses the S150 coil springs, but you could remove your hardware from the window to confirm that your dimensions match the ones shown on our product pages. Thanks for posting!
