Hello there. See either our S351-28 or S390-28. The only difference between these two balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You'll then have to choose a stamp option. I would check another balance of the same size to confirm the stamp code, as yours looks worn down to read, and I doubt it says 270. If in doubt, obtain the exact weight of your window sash. You can then match that exact weight with one of the weight ranges listed alongside each stamp option on the balance's shop page. |

Hey Derek. If it says 27C, we can skip weighing the window sash. That should conform to our stamp option of 2730. Let me know if you have other questions. |
