I need to replace our window balance on a couple of our windows. There is FT B 1 printed on the round tube, and it is 29" long. I attached some pictures. I believe the windows were installed in 2000 or 1999.
Any help would be appreciated.

I am ordering new series 900, 29" spiral balances. My existing ones have a white vinyl cover that goes over the spiral balance as you can see it in the photo. Do you know where I can purchase new ones of these?

Thank you,

Kevin

Hi there, Kevin.

I agree that the Series 900 is what you need if the outer tube diameter is 3/8". However, we don't sell the covers you're looking for. Your best bet may be to contact the original manufacturer of the window, whoever they may be. I am sorry for the inconvenience.
