Hello there. It looks like you have a 15-177 Coil Balance Shoe; please compare to confirm. This shoe uses our Series 152 Coil Springs. To know what spring weights to select, you need to remove the springs and look for stamp codes on the coil tape. If there are none, or you are uncertain, obtain the exact weight of your window sash. Let us know that exact weight and we'll work out what you need.
