coil balance replacement

Thank you for your patience during this very busy season. Your window's pivot shoe looks like it might be our 15-180; just go over the dimensions to confirm. This pivot shoe is compatible with our Series 190 Coil Springs. Look for stamp numbers on your old springs to confirm what spring weights you need. If there are no numbers, or you're uncertain, weigh your window sash. Give us that exact weight, and we'll work out what you need.
