Weather Shield windows balances missing

Hey there, thanks for writing in! The balances you have appear to have a non-winged top and a winged bottom, so your balance would be our one of our Series 350 Channel Balances. Specifically, you'll need the S350-25. Given that your balance weighs 16.2lbs, your stamp should be the 2430, which can support a sash weighing 15 to 19lbs.

For the window with the missing balance, you'll need to obtain the height of the visible glass from the window and then add 1 to it to get the length of the balance you'll need. Then you'll be able to select the length from the list of Series 350 Balances.

Once you've selected the correct balance length, you'll need to look at the chart below the product description. This will help you determine the stamp option needed for your balance to support the weight of the 24.8lb sash.

Our agent Deb let me know that you were not able to upload a response, however, she relayed your message. As explained, you would need to add 1" to the height of the visible glass. So you'd need the S350-36. You'll need to select the 3540 option for sash weighing 24.8lbs.
