Window Balance
Thanks for writing in! This balance can be replaced with either 5/8" S600-29 or the 3/8" S900-29 spiral balance to replace the one pictured here. You'll need to confirm the diameter of the tube to determine the correct series.
For the pivot shoe, you'll like need the 15-046 or 15-047. You'll need to confirm the width and thickness of the existing shoe to confirm the right replacement. Their dimensions can be found on the website.
You may also want to take a look at the pivot bars to see if they might need to be replaced as well.
Be sure to take a look at the video tutorials below for detailed instructions on removing/installing the hardware.
