Thanks for contacting us! The coil balance shoe you have here is the 15-177. Be sure to carefully review and compare the dimensions to confirm that this is the right fit.

This shoe is compatible with the 1/2" wide Series 152 Coil Balance, which is attached to the shoe using the 33-072 screw. To determine the correct coils for the assemblies, you'll need to remove your existing coils and look for any stamps/markings. For example, if your coil is marked with a 5, you'd need the S152-5.

If your coils do not have a stamp/marking, you'll need to obtain the exact weight of the sash and divide that by the total number of coils in the window.

To replace the covers, you'll need the 15-143 Coil Bushing, 15-144 Coil Bushing Cap, and the 15-145 Coil Support Barrel.

Take a look at the video tutorials tagged below for an idea on how to remove and install these balances.
