Thanks for posting. Take a look at our S370-35. Compare with your old balance to see if this matches up. For the stamp option, look for a stamp on the old metal channel that indicates this. if there is no stamp or you're unsure, weigh the window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option under the balance's product description. |
