sash balance pulley not working
Hello,
I don't recognize the type of balance assembly that your window uses at first glance but I'm going to have one of our senior experts take a look and see if it is familiar to them. We'll reach out as soon as more information is available. Thank you!
It looks like you are showing an overhead balance that fits at the top of the window frame. Unfortunately, the balance manufacturer discontinued this balance and there is no known replacement at this time. Our records indicate that the window was made by Premier Window Products in El Cajon, CA but I believe they went out of business. I'm sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions. Thanks for posting.
