Window balancer shoe

Hello, thank you for posting,

Please review the style and dimensions of the 15-177 pivot shoe that is compatible with the Series 152 coil springs. Compare below to confirm a good fit!

You will need to match up the number on the coil spring to determine the correct weighted option. If there are no markings, we will need to know the weight of the window sash to move forward. Also see the 15-143 bushing, 15-144 bushing cap and 15-145 support barrel. 

Let us know if you have any additional questions!
