Looking for a replacement coil balance

Question

I'm looking for the coil balance that would go with Coil Bushing 15-143 and Coil Bushing Cap 15-144. I see it says Use with Series 150 and Series 152 coil springs, however those coil springs don't match up to what our customer has. I've attached several pictures that will hopefully help with identifying. It has an 8 stamped on the coil so i assume that's and 8lb. The approx size of the window is 34 x 53. It's a single hung tilt in. Any info you can give me would be greatly appreciated.

Thank You,
Ingrid

Thanks for posting, Ingrid. I recognize this spring. It has been discontinued, I believe. I think you might want to check out our S150-8 and consider it as a possible replacement. You should also check out our 15-140 shoe.
