Sliding Window balance channel replacement

Thanks for your post! It's hard to tell without seeing the balance. Are you able to provide me a picture of the entire balance?  The stamp just indicates what the strength of the balance is. You will have to get as exact a measurement as you can from your shoe to know for sure.

Thanks for the additional photos. Take a look at both our S380-20 and S385-20 channel balance. These looks compatible with the exception of the depth measurement of the bottom balance shoe. For the Series 380, the depth of the bottom shoe measures 1" and for the Series 385 is 1-3/32". You will need to measure the depth of your bottom shoe, like in the diagram below, to determine which balance is the best match. Whichever one chosen will go with the 1930 option.

Sounds great. Be sure to get back to us and let us know how everything works out.
