S900-28 Yellow Tip Spiral Balance

A quick learner from Arkansas says:
September 5, 2022
I ordered two S900-28 from your company and upon installation, the spiral rod pulls completely out of the metal tube when the sash is closed. There is about 1/2" space between the bottom of the metal tube (not the yellow tip but the aluminum tube itself) and the spiral rod where it has pulled out of the tube. I measured my old spiral rod and it is 1/2" longer than one I ordered from you (when the spiral rod is pulled out of the aluminum tube and the lengths are compared).

Obviously, I need a longer spiral balance. Should I order a 29" or 30"? If these lengths are not available with a yellow tip, which color should I choose?

Thanks.

Hi there!

Before we recommend a different length, we'd like you to confirm the length of both the outer tube and the inner spiral rod. Can you also show us a photo of the end of the spiral rod?

Thank you!
