I have two double hung, non tilt windows weighting 14 pounds with broken springs in the lifting rails, as noted on the attached pictures. The rail is 16" long and 1/2" wide. The rail has a mark "16HD B.S.I." The rail has a lifting lug on a string coming out from the bottom of the rail. I don't see such a rail in your examples.
Thanks,
Don

Thanks for posting, Don. This looks like it might be our S751-17 Tilt Window Channel Balance. You will need a stamp option of 16HD. Let us know if you have any other questions. |
