Greetings- From your photos, it appears you need the S751-27 channel balance that comes with our 15-014 balance shoe. Your spring weight option will be 26TG for a sash weighing between 24-31 lbs. Check out the media guide below for additional help installing a ribbed tilt channel balance in vinyl jamb liners. |
