Hello there. This exact pivot shoe was recently discontinued and is no longer available, however we believe our 15-177 may work as a substitute. This shoe has similar dimensions to your old one, and is compatible with the same type of coil springs: our Series 152. If the sash weighs exactly 22 pounds, you'll want an S152-6 6 pound coil and S152-5 5 pound coil on each side of the sash. This will equal 11 pounds of support on either side of the window, for a total of 22 pounds of support overall. If you need new housing for these coil springs, see our 15-143, 15-144, and 15-145. These sandwich around each individual coil spring to form a housing assembly. Let me know if you have further questions, and if you give this a shot, let me know how you make out.
