double coil balance replacement

My window is 14lbs. The coil balance snapped in two on both sides - I'd like to replace the entire piece (not just the coil) as they are 10+ years old. The issue is the width of the window channel. I've recently ordered what I thought was the correct replacement part but they are not wide enough. My parts measure 1 1/4" at the base and 13/16" width (window channel).

Hello, thank you for posting!

Your pivot shoe is an older version which has been discontinued. Please watch the below video for a step by step guide detailing the newer parts available for replacements. Please let me know if you have any questions.

Thank you for the help. I went back to look at the coil springs (part S159) and I see it goes up to 12.5 lbs. Will that be enough - again, my window is 14lbs.
Thanks

The weight range you see is how much weight an individual coil can support. The coils on each side of the window are added up to support the whole weight of the sash. For 14 pounds, I would recommend (2) S159-3 on each side or (1) of S159-6 on each side of the channel. Please let me know if you have any questions.
