I need to identify this spiting. I need 6 of these. Windows are roughly 25 years old. Also note that the window weigh about 22 lbs each.

This appears to be either an S380-33 or S385-33 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. For a new stamp option see the 3230.
