Hello, I have attached a picture of a sash spring. Unfortunately, I do not have a picture of one installed. They do not have a colored tip at the end to represent spring strength and they are 29 inches long and 3/8 inches wide. Also, do you have a exploded view of the attachment to the sash? The small metal piece is broken on the one I'm working on.
Thank you, Jason

Hey Jason. Is this from a tilt-in window? If so, It would be the S900-29 based on the dimensions you give. To know what color tip to select for the replacement, weigh the window sash the spiral balance supports. You can match that exact weight with the correct color tip option. As far as the metal piece you are referring to, can you please specify what it is or send a photo? Also let me know if this is in fact not a tilt window. Many thanks.
