Identify this spiral balance please

A home owner from Bensalem Pa says:
In the photos the spiral balance is 9/16" thick.

Has a blue tip.

Measures 35" long.

Is this P/N S600-35? The S600-35 shows a red tipped end, not a blue as I have.

I agree, the S600-35 looks like a good match. As for the color tip option, can you confirm the weight of your sash? That will help us find the best match.

It wont be easy to get the weight of the sash. It's in a rental unit a few hours away.

What can you recommend for the color tip? Is there only red and black available?

I think our S600-35 with a Red Tip will be sufficient for residential windows. The black tip is used for commercial windows. We could make it in Blue, but it would have to be custom made and is uncommon for this size, anyway. That said, I agree with Tom that weighing the sash would be best if you want to confirm. There is that off possibility that you have a special case.
