Thanks for posting. I agree, the S395-18 looks like a good match. Your stamped number of 17 3 corresponds to our stamp option of 1730. This is for a window sash weight range of 12 through 14 lbs. Is that correct? You can always weigh your window sash if you are uncertain. Let us know what you think. |
