Balance replacement
Hello, thank you for posting,
The video you are referring to is a similar coil balance function, but not the exact parts needed.
Your original pivot shoe has been discontinued, but we recommend comparing the 15-177 as a replacement option. This pivot shoe is compatible with the Series 152 coil springs.
Each coil should have a number stamped on the metal that indicates the weighted option needed. If there are no markings present, please provide the weight of the window sash to move forward.
Also see the 15-143 coil bushing, 15-144 bushing cap and 15-145 support barrel. Please review and let me know if you have any questions!
Thank you for confirming,
For a 13.7 pound window sash, you can use (1) S152-7 coil spring on each side of the window sash.
Yes, the support barrel goes inside of the coil spring and then the 15-143 bushing and 15-144 bushing cap sandwich the coil on each side.
Let us know if you have any additional questions!
