I recently purchased two pairs of Better-bilt window latches; item number 26-351. I do not know the series of Better-bilt windows. The windows are 3050 single hung windows. I want to buy two pairs of spiral balances for the same windows.
The tubes are 30" long. The diameter of the tubes is tubes is 3/8". There is no color on the ends. Can you help me identify the correct parts?
spiral balances?

Hello there. If it's a tilt window, and the spiral balance outer diameter is 3/8", and if the tube up to but not including the tip is 30", then you have an S900-30 Spiral Balance. You will need to weigh the window sash to determine the color tip option to select. Let me know if you have further questions.
