Hello!

Thanks for reaching out to us. The 15-228 pivot shoe looks like a match for yours. The 1/2" Series 160 are the compatible coil springs. Since your old double coil support is stamped with #9, see the S160-09 9-pound spring. If you need new supports, see the 15-150D and 15-150S respectively.

Please let us know if you have any questions!

Thx! I found I also need triple springs, four sets, marked 7.5#. What causes the windows be tight? And how do I figure what size seals and fuzziesI need and how they are sold, by peice or foot.
Can you tell me, is there an adjustment for frame bowing?

See the S160-07 7.5-pound spring and the 15-150T triple coil support.

Our full selection of weatherstripping can be found here. The video below will go over how to ID weatherstripping. For pile weatherstripping, you will have to measure the pile height and the base width and compare the specifications to our selection of pile.

The bowing of the frame is likely making the window feel tight. Unfortunately, frame bowing is outside of our field of expertise so we recommend contacting a local professional to assess the problem.
