Thanks for posting. Your pivot bar is similar to our 26-327. It looks like yours was installed using the rear most hole, so you may want to check the hole spacing measurements on our 26-327 to make sure the right hole is in the proper position.
Your weight is a little confusing. Did you weigh the balance? When determining the proper spring strength option, you should measure the sash, instead. Since the balance's job is to keep the sash up, knowing the weight of the sash is the best way to determine what color tip option you need. You can compare the weight you get to the chart on the S900-26 store page. |
