I could use some help identifying the correct channel balance. I have narrowed it down to an S380-29 but I don't know what the correct weight range is. My existing channel balance is stamped with 28D. The SWISCO options are 2810 thru 2860. Do you know which option correlates to a 28D?

A stamp of 28D usually corresponds to our 2840 option. Just weigh your sash just to make sure that's correct.
