Pivot Shoe replacement
You'll need to confirm the exact length of the your balance tube to determine the correct replacement match. If it is 17", you'll need the S600-17. If you find that it is 17.5", please let me know. Be sure to double check that the balance diameter is 5/8" as well.
Since your balances have a green tip, I'll also need to know the exact weight of the window sash. This balance is not available in that tip color.
Your pivot shoes look like they could be a match for the 15-015 Pivot Shoe. To determine if this will work for your repair, carefully review the dimensions and compare them.
If the dimensions aren't a match, I'll need to know the width and thickness of your shoes.
I measured the balance again and it actually looks like 16" with the spiral pushed all the way in. The diameter is 1/2"
A single sash weights 16.5ish pounds
The channel for the shoe looks to be 1"wind. I have a black stopper piece that keeps them form getting out though. Sorry i put the sashes back before i could measure them
Hello,
If you are certain the balance measures 16", you'll need the S600-16. The blue tip option will support a sash weighing 9 to 28lbs.
Unfortunately, measuring the channel will not help to confirm if the shoe is a match. You will need to remove it and compare the provided dimensions.
