I need to replace two of these window balances on a non-tilting window. Channel length is 21". Window is Milgard, installed in 1998. Please help in identifying this part.

Thank you,

Margaret

Hi Margaret. It looks like you have either our S380-21 or S385-21. 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 choose 2050.
