Certainteed coil balance

A home owner from Illinois says:
Hello,
My certainteed window coil balance has broke and I need some help figuring out which coil balance I need to order. When I went to take the old coil balance out I found that there are two coils on either side of the sash. The numbers stamped on the side I took off are SA 406 500 and LA 406 500. The coils are 1/2" wide. Any information would be greatly appreciated.

Thank you

Jonathon

Thank you for your patience in this matter. We are still researching possible replacements for this housing. However, to help us in our search, could you please give me the dimensions of the plastic housing? Please make sure to include the height and width, as well as the diameter of the drum itself.

The dimensions of the plaastic housing are: 1.50"long x1.25"wide x1"deep. The drum diameter is 1.25". Hopefully this helps. Thank you.

Thank you for the dimensions. However, the drum diameter you mention appears to be for just the retaining cap on the end. The drum dimension I need is beneath that; alternatively, we could use the inside diameter of your coil.

The drum diameter is 3/4".
