Spiral Window Balance Parts
The spiral balance you are looking for is our Series 600. Please provide us with the tube length of the balance as well as the color of the nylon bearing where the spiral comes out. The pivot shoe you show has been discontinued. Depending on the thickness of your shoe will determine whether or not the 15-046 or 15-188 will work best for you.I encourage you to review some helpful media guides on this page that shows the installation and removal of this balance system.
Sure, if that's what you wanted to do. I think it'll be easier to just measure the old shoe, but if you wanted to do it the other way you can see our return policy here.
We will be placing an order for all the parts soon.
I would recommend our S600-21 spiral balance with a red tip color option.
