Part for AI SIDE WINDOW

Hello, thank you for posting,

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

Alternate image for 15-177

The coil spring should have a number marked on it that indicates the weighted option needed. 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. Take a look and let us know if you have any additional questions!
