28 1/4 3 Caldwell balance

Quick Learner from Stillwater, OK

Hello,

Need to replace 2 Caldwell window channel balances. They were installed in 1993 when the house was constructed. One balance has marking "28 1/4 3 Caldwell CM". The other one has no identification. The window opening width is 33.5"

Thank you,

George

Hi George,

I'm afraid I cannot identify what you have based on this information alone. The stamp only indicates the spring strength calibration and is not otherwise used to identify your balance. 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.

If you can't find a match here, please show us a picture of the top nylon attachment and a picture of the bottom nylon attachment and we will do our best to find a replacement.

Casey,

My channel balance is marked "Caldwell CM". It is ink dot stamped as "28 1/4" and, metal to metal, it measures 29 1/4". The "3" is separate and I guess that is the spring weight/load number. Photos are attached.

Ah, I see. Thank you! I believe this will have to be specially made, due to the length. I think we have everything we need to get started, but I would like you to confirm the depth of the bottom shoe. I think you have either our Series 390 or Series 351 depending on what size the shoe is. 

Can you also tell me how many you need?

Once you've confirmed which of those Series you have, and the quantity, we'll email you an order link and price quote.
