I'm sorry to say that we don't have a version of the 39-187 with that size arm. It may still work as-is, but if not then you will need to move the attachment bracket on the sash to make up the difference. That will require drilling new installation holes. |

I'm not sure that I understand your question. Based on your first post, I was under the assumption that you were measuring the link arm. That's the arm that connects to the sash. Were you measuring something else, instead? |
