Replacement balance for Pella 150

A home owner from North Myrtle Beach, SC says:
May 18, 2023

I need a replacement balance for a Pella 150 double hung window manufactured in 2021. The balance is a 2 coil constant force balance (shown in catalog). I'm not sure if it comes with the frame attachment screw or not, but I need one of those also (pictured). If you could direct me to the parts that I need, I would appreciate it!

Also, I need a replacement balance pocket cover set (part in catalog attached) for a Pella 150 double hung window manufactured in 2021. Do you carry this part?

Thanks,Rob

Thanks for reaching out! We do not carry your exact coil balance assembly but our 15-251, Inverted Universal Single Support should work great as a suitable replacement. Look over the dimensions for to determine if this part will work as a replacement for you.

Measurements of 15-251
Measurements of 15-251

These are compatible with the 1/2" thick Series 160 coil springs. Since your existing housing is stamped with a 10, you'll need the S160-10. You may also need the 16-031 mounting bracket.

You'll need to reuse the existing screws or purchase them from a local hardware store as we do not carry an exact match for them in our inventory.
