Hello!
I'm replacing the balance coil spring assembly in a double hung Polaris window. I'm sending some pictures. The coil width is 11/16" and stamped 10FH; the shoes are stamped G10.
Please advise on Swisco replacement parts.
Thank you.

Hi there!

Thanks for reaching out to us. Our Series 210 looks similar to what you have here. I recommend you remove yours from the window to confirm the dimensions line up with ours. However, note that the spring is 7/8" thick, not 11/16". Can you double-check that measurement for us, just to be safe?

Hi Emily,

So here's another pic. It's closer to 3/4" but definitely not 7/8". However, I'm willing to give the 210 a try, thanks!

One more thing:
So I need a pair of replacement springs. Are they designated left side / right side?

The Series 210 balance can work for either the left or right hand side interchangeably. That said, we always recommend replacing both balances for a single window sash at the same time.
