Question

I have determined I need the 385, the wider foot and wings. But am not sure of the sash weight. The code on the channel is 26 4 AW CMC 7. What do I need for weight option
thanks

Thanks for posting. For an S385-27 with an old stamp of '26-4', choose 2640 as the new stamp option. This designates a balance that can support a window sash in the weight range of 19 through 26 pounds. Let me know if you have further questions.
