broken coil balances

Question

Greetings,

Broken coils on both sides of the lower sash of a bathroom window. It looks like there is 1 coil only per side. The problem I had so far was removing the parts. I pried one out but it broke. (as seen in picture 2 attached). The window rail, where the hardware is moving through, doesn't have a slot where the parts can be removed. I didn't find markings on any of the parts. The window pane is vinyl, 32" x 22" x 1.5", pretty standard, if it helps with the weight. If needed, I can weight it. Please let me know if you carry this type of hardware and if you have any suggestions on how to remove / install them. Thank you so much.

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.

The coil housing pivot 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.

The metal mounting bracket that secures the coil in the window channel is part 16-024.
