Balances and cams

Thanks for posting! Your exact coil shoe is no longer made but the good news is we do have a replacement shoe that should work well as a suitable replacement. Take a look over the dimensions for the 15-259 Coil Balance Pivot Shoe. Carefully compare them to your shoe to confirm this would be a fit in the window channel.

This shoe is uses the Series 159 Coil Balance. To determine the right spring strength to support your sash weight, take a look at the existing springs for any stamps/markings that will indicate the amount tension the coils will need. Although, since this is a new balance assembly, it may be a good idea to obtain the exact weight of the sash, down to the ounce, and divide that number by the number of coils in the window.

You'll also likely need the 15-256 3/4" Coil Double Support.

Your existing pivot bar isn't likely to be compatible with the 15-259, so you'll need to replace it with the 26-083 2-1/2" Pivot Bar.
