Hello there. Is this spiral balance for a tilt window? If so, measure the tube diameter. If it's 3/8", you'll need the S900-29. If it's 5/8", see the 600-29. To know what color tip to choose, weigh the window sash. You can use that exact weight to choose the correct color option. For a charging tool, see the 75-006.
