Vinyl window hardware

Question

I can't see any markings on the part. I don't want to remove it till I have a replacement part. It is in the frame of the window and helps the sash move up and down. The window/ sash is stuck and won't move up due to some metal coil sticking in the frame. Please help me identify the part.

Thanks for reaching out to us. I'm afraid I can't be sure what you may have from these photos. The hardware is too obscured by the window sash and track. The 15-087 and 15-086, which use the S180 springs, come to mind but this is an educated guess. You will have to remove the old parts to confirm if they match up. The video below will go over how to do so.
