Thanks for contacting us. I believe we can help, but this balance will have to be specially made. First, you mention that there are no nylon attachments. Just to be clear, this balance never had any nlyon attachments in the first place, right?
If not, I would make our S770-19 but with the bottom clip swapped out for the 62-105 hook. Before we begin, can you just confirm the weight of your sash? We will need that so we can calculate the proper spring strength. |
