Need assistance on selecting the right stamp option or sash weight range. I have already determined the model type which is 380 and the length of the 380 channel which is 29 inches. The top and shoe of the balance have wings which is the 380 series and the depth of the shoe is 1inch. The size of the window is 45.5 inches x 32 inches if that helps. There are markings on the original balance which is "28 4 AX CMC 11". Any assitance on selecting the right stamp option is greatly appreciated.

Hello! I agree, as long as the shoe depth is 1" then our S380-29 should work well for you. As for the stamp, "28 4" usually corresponds to our 2840 option, but you can always weigh your sash on a scale to verify.
