Trying to find replacement

Thank you for reaching out to us. Sure, we can help with this. It appears the Series 795 is what you want. Just note that this comes with the 15-195 closed cam shoe but I can't be certain it's what you have. You may want to remove your old one from the window to confirm.

One important detail to note is that the Series 795 attaches to the top of the track using a screw, not a hook. If yours needs a hook then let me know; we can still help but your balance will have to be custom-made.
