WINDOWS FROM 2003

Thanks for reaching out! Your spiral balances look like they could be either the Series 900 (3/8" diameter) or the Series 600 (5/8" diameter). To determine which balances are needed for your window you'll need to remove them from the window to confirm the diameter and the other information needed to properly identify your balances.

You'll also need to remove the shoe from the window as well. I am unable to identify it because the view of it is obstructed by the window channel.

Take a look at the videos below for the details about what we'll need to identify your balances and how to remove the pivot shoe from the window.

To determine which balances are needed for your window you'll need to confirm the diameter of the balances. As explained, they could be either the Series 900 with 3/8" diameter or the Series 600 with a 5/8" diameter. You'll also need to confirm the length.

Your shoe looks like it could possibly be the 15-045, however, to confirm this, you'll need to compare all of the measurements. The height is important but the thickness and the width are just a bit more important to confirm, especially the thickness. To confirm that, you'll need to have them removed, unfortunately there isn't any way around that.

Dimensions for 15-045

I strongly recommend taking a look at the videos provided above for the details needed to select the correct balances for your windows as well as how to remove the shoe. 

These do appear to be the 15-045 pivot shoe. The spiral balance you'll need is the S900-35 with the yellow tip.

Please let me know if there is anything else I can assist with.

These balances are made with a metal tube that encases the internal spiral mechanism. Although made differently from what you have, they will still work the same. We've recommended these for the type of balance you have, and used them ourselves, many times. 

If you believe the tip on the balance to be white, then you'll need to select it at checkout. If you are unsure, you can use the chart below the product description of the balance to double check the tip color you'll need based on the weight ranges shown.
