Hm... your stamp is not typical for this balance. You will need to confirm the length of the metal channel and the weight of sash. We have a chart on every Series 795 store page that tells you how much weight each option supports, so just refer to that once you know the length and weight "option."
However, it's important to note that our Series 795 installs using a screw tab, not a hook. If yours has a hook, you need to tell us, because the balance will have to be custom made in that case. |
