The S152-9 would attach to the side of the 15-177 shoe with the 33-072 screw. The F on your coil could indicate that it is a 6-pound coil but one 6-pound coil on each side would not support the sash weight you've provided. For that reason, you would need the S152-9 for each side to support 18 pounds. |
