Pivot balance shoes with coil springs

Question

I need the pivot balance shoes with coil springs for 6 windows. So, I need 6 left and 6 right.

The pivot shoes are 1 1/4 to 1 1/2 inche wide and 1/2 inch thick. They are about 2 inches tall without the spring.

The windows are all the same and weigh about 24 pounds.

Thanks,

Greg

Hello there. This looks like a 15-180 Pivot Shoe, 15-186 Single Spring Support and 15-182 Drum. This setup works with Series 190 Coil balance springs sold separately. A single spring setup would suggest something lighter than a 24 pound sash. Please double-check to determine the spring weights needed. See below.
