Hi. Our PRISM double hung window no longer stays in position or holds its position. The first two attachments show the parts that were sitting in the window track. The third attachment shows I believe, the coils that should be holding the window sash. The last attachment shows an id number in the window. Both upper and lower sashes do not stay in place. Can you please advise what parts we would need to order?
Does the upper sash also have coils?
Will we need some kind of track spreader?
Thank you.
