I'm looking for what appears to be 10 lb coils for my double hung windows. I believe they're aside windows in Michigan.

Hello!

Your pivot shoe is a match for the 15-177, which uses the S152 coil springs. We don't have a 10-pound coil spring, so you'll need to use two S152-5 5-pound springs on each side of the window. You will also need an additional 15-143 bushing, 15-144 bushing cap, and 15-145 barrel.

Please let us know if you have any questions.
