Thanks for posting. I'm not sure exactly what it is you need. You mention a plastic part in the side track, and show a picture of a coil balance cover. Is that all you need, or did you need the whole coil balance? In what was is it broken?
I'm afraid we will not be able to replace the frame on your sash.
Thanks for your reply! I suppose I need the whole part, not just the cover. I tried to get them from Milgard but they were no help at all, and would not even let me buy the parts. If you have these, I would like to order 6-10 of them.
On the sash, only the part on the right is broken. If we had that part, we could fix it. We could not find a part number on it anywhere.
Thanks for your help,
Marien
We will need more photos, with dimensions, to further help you. On the other hand, we pulled up some parts related to the code number you gave. You can check them out on the right, and see if anything helps you.
