Coil Balance parts

Home Owner from Willowick, Ohio
These are off of a Pella 27.5x 37.5 bathroom window. Looking for replacement parts. Stamp on coil is hard to make out, looks like "5"

Hello there. I believe this shoe might be an older version of our 15-228 , but look over the dimensions cited below and let me know if they match. If so, this shoe uses either our Series 160 1/2" thick springs, or our Series 165 3/8" thick springs. Compare both with your old springs to see which you need. Let me know if you have further questions.

Dimensions for 15-228

Great. In that case you need the 1/2" Series 160 coil springs. A '5' stamp would suggest you need the S160-05 5.5 pound springs, but see the video below that shows how to choose the right spring weights for new coil springs, just to confirm. For new coil housing for a single coil, see the 15-150S.
