Coil Balance and Shoe Replacement

Thanks for posting! Your coil balance housing looks similar to our 15-087 coil housing pivot. Carefully review and compare the dimensions to those shown below to determine if this is the correct replacement. I am confident these are the replacement you'll need.

Detail of 15-087

This housing is compatible with the Series 180 coil balance spring. To determine which spring is needed for your housing, you'll need to look for any stamps/marking on the metal coil. If there are no stamps/markings or they cannot be read and/or cross-referenced, you'll need to obtain the exact weight of the sash. Then you'll take the sash weight and divide it by the total number of coils in the window.

Yes, the S180-7 will work fine as a replacement. As long as the coils are within 1lb of the window weight, the window should still function properly.
