Pennco Window Balances

Hi Ron. We'd be happy to help you replace these channel balances for your window. To assist though, we'll need to see the balances out of the window; specifically, we'll need to see pictures of the nylon attachments or fittings on either side of the balance, as well as a picture of any stamp code on the metal channel. The length of that metal channel, not including the nylon fittings, is also important. From there, we can identify what you need. For details on how to remove and replace your channel balances, see the video below.

These photos are great, thank you. Have a look at our S380-28 balance. This comes with the 19-005 balance top attached and 15-005 bottom balance shoe. Compare your part with ours to see if this is a match. If it everything looks correct, then you can go with the 2740 option that holds a sash weight of 19-26 pounds. 

Have you had the opportunity to measure the depth of your bottom shoe and compare it to ours? If not, go ahead and do so to confirm whether or not this is a match. Don't worry so much about the style, I don't think yours is different enough to make an impact on how it works. The size is the most important detail in this case. As long as yours is 1" deep, then 15-005 should work well.
