Hi
My channel balance is half inch wide and 21 inch long
But the stamp reads 20 3 BP Caldwell so I am unsure of the weight range that correlates with swisco's 20xx series
Thank you
Stamp doesn't match swisco's

A 20 3 stamp usually corresponds with the 2030 option, but you can always weigh your sash to confirm.
