Coil balance (no identifiable mfgr.)

A home owner from Franklin, Tennessee says:

Wish to order the above which appears to be

S152. It is the left coil spring (as you face window from inside) and has the number 8 on it which I presume identifies the window weight. Want to order two to replace both sides. Please advise what part number to order and is the part the same for both sides?

Thanks,

Frank

Hi Frank, thank you for posting,

Your balance assembly resembles an older version of the 15-180 pivot shoe that is compatible with the S190-840 coil spring. (1) spring on each side will equal a 16 pound sash weight, please compare. Also review the 15-182 bushing and 15-186 balance clip if needed.

Review all dimensions to confirm a good fit and let us know if you have any additional questions!
