Single Hung Pella Window Balance Replacement

Thanks for reaching out to us! Your Pella coil balance assembly appears to have use an inverted universal support of some sort. I believe you can use our 15-251 Inverted Universal Single Support as a suitable replacement, however you'll need to carefully review the hardware to confirm this will work as a replacement. Please let me know if your assembly uses more than one coil balance spring.

Measurements of 15-251

The coil spring compatible with this support is the Series 160 Coil Balance. Since your housing is stamped with a 10, you'll need to select the S160-10.
