Thanks for reaching out to us! Your pivot shoe appears to be the 15-177 Coil Balance Shoe. To determine if this is the correct replacement, you'll want to remove the shoe and compare the dimensions below. Alternate image for 15-177
This shoe is compatible with the 1/2" thick Series 152 Coil Balance secured to the shoe using the 33-072 screw. To determine the correct spring for your assemblies, you'll need to look for any stamps/markings on the metal coil. If there aren't any or they are hard to read, I would suggest obtaining the exact weight of the sash. Once you have the sash weight, you'll divide that number by the total number of coils in the window. If you cannot reuse your existing covers, you'll need the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and the 15-145 Coil Support Barrel. |
