Need to replace these parts

Thanks for writing in! Your coil balance housing looks similar to our 15-087 coil housing pivot. To determine if this is the correct replacement, you'll need to compare the dimensions, shown below, to your existing housing. Although, 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 is part 16-024. This is used to anchor the coil balance in the window frame.
