There are a few things to consider here. First, be sure to measure only the length of the metal channel; do not include the length of the plastic shoe or plastic top. A 26 inch balance marked with a number 24 is uncommon enough to warrant double-checking the measurement.
As for the stamp option, unless you can find the four-digit stamp (likely starting with a 2) on the old metal channel, you will need to remove and weigh your window sash. Update us about the old balance and we will try to confirm the proper replacement. |

Thanks for getting back to us! That makes a lot more sense. The Series 350 comes with the 19-002 top and 15-004 bottom, so as long as those match you should be okay. A stamp of "25 2" usually corresponds to our 2520 option, but like Mike mentioned you can always weigh your sash to confirm. We have a chart on the S350-26 store page that tells you how much weight each option can support.
