Replacement Sash Balance and Sash Shoes for Milgard Aluminum Frame Window

A home owner from West Toluca Lake, CA says:

We have several older Milgard windows that are 45"W x 69"H, Aluminum frame single hung, and non tilt. Some of them have a need to have the sash balance and/or sash shoes replaced. I have removed one of the sash balances and measured it to be 33"H (from metal tip to metal tip, 1/2"W, 1/2"D. The sash balance is stamped with the part # 32 4 JO Caldwell. Can you help me match the Swisco part(s) that would be equivalent? Thanks in advance. Chas

Thank you for the images! I'm afraid I do not see the bottom shoe, though, just the top attachment. That, at least, looks like our 19-005, but I cannot name the Series without also seeing the bottom shoe.

I recommend that you look at our Channel Balance Home Page and follow the steps in order to find the Series that best matches what you have.

Great, thank you. Check out our Series 385 channel balance and see how well this matches your hardware. Take special note of the shoe. The Series 385 uses our 15-004, so it's important that your own shoe has the same dimensions.
