Hey there, thanks for writing in! Your pivot shoe looks a lot like our 15-180 coil balance shoe. To confirm, carefully compare the measurements to determine if this is the right fit for your window. Alternate image for 15-180
The compatible coils springs are the Series 190 coil balance springs. To determine the spring strength needed for each coil, you'll need to check for any stamps on the metal coil. You may also need the 15-181 double support detent clip and 15-182 coil bushing. |
