Thanks for posting. The part you're looking for is known as a balance, not a sash. The sash is the glass panel that the balance physically supports. This is an important distinction because I'll need you to get me some information regarding your sash before I can confirm a match.

First, to determine the length of the balance you need, I would like for you to measure the visible glass on your sash. Give me the width x height. I would also like you to remove your sash from the window and place it on a scale, then give me the weight you get. That will allow me to make the best recommendation.
