Thanks for posting. This looks like the 15-180 Pivot Shoe, which works with Series 190 Coil balance springs sold separately. For a 22 pound window, use the S190-540 5 pound spring and S190-640 6 pound spring, one each for each side of the sash. That will give you 11 pounds of support on either side of the sash, for a total of 22 pounds of support.

For new coil covers, see the 15-181 tandem housing and 15-182 drums.
