Hello, Your channel balance resembles the S385-15 with a 1-3/32" deep bottom fitting as shown below. If there is no stamp on the metal channel, you'll need to weigh the window sash that it supports and follow the chart below from the balance product description to choose the corresponding strength option. Thank you! Stamp Option Sash Weight Range 1410 4 to 6 lbs 1420 6 to 10 lbs 1430 10 to 12 lbs 1440 12 to 13 lbs 1450 13 to 17 lbs 1460 17 to 20 lbs Close up view of the S385 balance shoe.
