Spiral balance

Question

Hi, I'm replacing the spiral balances in my windows. They weigh 20 pounds and the tube length is 30 inch and they are tilt.  What model number  balance would you recommend? Thank you. Matt

Hello there. It sounds like you need either an S600-30 or S900-30 Spiral Balance. Measure the diameter of your old balance's outer tube. If it's 5/8", go with the Series 600; if it's 3/8", choose the Series 900. For a window that weighs 20 pounds, select a blue tip for the S600-30 or a green tip for the S900-30. Let me know if you have further questions.
