Hi there! The part shown here is called a spiral balance. I believe you may have a tilt window so if that's the case, see the 3/8" diameter Series 900 or 5/8" diameter Series 600. You'll want to measure the outer tube of your old balance to confirm the proper Series. There should also be a colored tip on the balance. If there isn't one or it's too faded, get back to us with the exact sash weight and we can work from there. Do you need the pivot shoe as well? If so, I will need you to write out the thickness and width to narrow down some options. It's also a good idea to replace the balances on both sides of the window! Pairing an old balance with a new balance will cause the new one to wear out much faster since it has to pick up the slack for its older counterpart. |

Thank you for the additional photos! The balance tube and pivot shoe look like they could be the Series 900 and the 15-212 but I recommend reviewing the specifications of each to confirm they align with yours. The colored tip of the balance also appears to be too faded to make out. In that case, you will need to weigh the window sash on a scale to determine the appropriate tip color. Alternate image for 15-212
