I need to identify the spring part #. The sash weighs 13 lbs. and the spring is 1/2 inch width.

Hello!

The 15-177 can replace your old pivot shoe. You can use one S152-7 7-pound coil spring on each side of the window for 14 pounds of overall support. If you need new coil supports, see the 15-143, 15-144, and 15-145 (sold individually).
