Hi there!
Could you show us a picture of an undamaged version of your top and bottom nylon fittings?
Thank you!

Thanks for getting back to us. Emily is not in today, but I'd be happy to help. This appears to be either a Series 380 or Series 385 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. The image below depicts the difference. Compare both with your old hardware to see what matches best. To determine how best to measure the length, as well as read the stamp option, see the video below.
