SWISCO - The Replacement Hardware Authority

sash window balance

A home owner from California says:
Hello. Can you help identify the correct part I would need to replace several of the window balances in my home. The only identifying information I have is the following information that was imprinted on the balance "30 3 AT CALDWELL". It measures 1/2" wide on the backside. The total length is 32" with the plastic hardware on the ends. Enclosed are two pictures. I would require four of these window balances.

Thank You

Thanks for posting! Before I can offer an applicable replacement for this channel balance, I just need to know a bit more information about the bottom attachment. Please take a look at our 15-004 and 15-005 channel balance shoes, and note their depths. As you can see, they are 1-3/32" deep and 1" deep, respectively. Which one more closely matches your own bottom attachment?

Hello. It measures 1 3/32 so it is closer to the 15-004 shoe.

Thank you. In that case, take a look at our S385-31 channel balance with a 3030 stamp option. Does that look about right? Make sure to double check all your information to make sure that it matches this set up.

Thank you that will work.
