Channel Balance

I am sorry to hear that you're having trouble uploading photos to us. You can email your photos to help@swisco.com. Just be sure to include your reference number, D164806. Thank you. 

Hey Shar. Yes, this definitely looks like the S351-28 or perhaps also the S390-28. The only difference between these two balances is the depth of the bottom nylon shoe, which can be thought of as the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. You will need a stamp option of 2740. 

I think you are on the right track here. Again, the depth of the bottom shoe can be thought of as a 'heel to toe' measurement, just beneath and perpendicular to where the metal channel ends. With the Series 380, this depth is 1"; with the Series 385, the depth is 1-3/32". Despite a very small difference, it does affect window compatibility. Now, it looks possible you have a show that is slightly greater than 1" deep--in which case you'd want the Series 385. But I caution that reading measuring tape from photos is never too reliable, as the depth perception can be misleading, so do your best to confirm this. Let me know what you decide on.
