Question

this is the balance parts for my windows. there are no part numbers on these items. In your part listings you show a # number next to the items, 3, 4 ,7 lb. is this the lifting strength of the balance spring. I have a widow sash that weighs 16 #. What selection would I use.

See our 15-177 Pivot Shoe. This shoe uses our Series 152 Coil Balances. If your window sash weighs exactly 16 pounds, use the S152-8 8 pound spring on both sides of the sash. This would equal 16 pounds of total support.
