Hi

I need replacement spiral balances. the dimensions are in the photographs and the diameter of the tube measures 9/16" (so I guess it is a 5/8" tube).

For this kind of old wood sash, we like to recommend our Series 500 spiral balance and 17-012 bracket. This hardware has been used on wood sashes since the 40's. Check it out and let me know what you think!
