Replacement Window Components

Hey there,

Thanks for writing in! Your coil balance pivot shoe looks like our 15-111. Carefully compare the measurements to your existing pivot shoe to confirm that this is the right fit.

The compatible coil spring is the Series 160 Coil. To determine exact which spring is needed for your window, you'll need to obtain the exact weight of your window. Once you have the weight, you'll need to divide it by the total number of coils in the window. This will give you the spring strength needed for each coil.

We do not carry an exact match for the cover you have however, part 15-150D should work fine as a replacement.
