The pivot shoe you have is our 15-180 Coil Balance Shoe. Although, you'll still want to be sure to compare the dimensions to be absolutely sure this is the right fit. Take a look at the diagram below for reference.

This shoe is compatible with the Series 190 Coil Balance secured to the shoe using the 33-073 screw. To confirm the springs needed for your assembly, you'll need to look for any stamps/markings on the metal coil. If there are none, you'll need to obtain the exact window weight and divide it by the total number of coils. Then, on the list of balances, the first number after the 190 will be the weight you'd need to select. For example, if your window ends up weighing 24lbs, you'd need (4) 6lb coils. Therefore, you would need the S190-640. You may also need the 15-181 Double Support Detent Clip and the 15-182 Balance Bushing. Thanks for posting! |
