26 5 fw cmc 10 window sash

Hey there,

Your window balance is assembled similar to either the S378-27, S380-27, or the S385-27. To confirm which of these is the correct replacement, you'll need to measurement the depth of the shoe.

You can very likely use the 2650 stamp option but it may be a good idea to double check that your sash weight falls between 26 to 30lbs.
