I need to replace two of my window channel balances. They are labeled Caldwell 28 4 DM. They measure 29 inches and go in a window that is 30.5 inches. I think it's the S350-31 but I think the shoe is different than the 15-004. Also, I do not know what weight I need.

How about our Series 390 channel balance? This comes with the 15-001 shoe, which may be a better match.
Based on your stamp of 28 4, I recommend our 2840 stamp option.
