This measured 15 inches long but I did not measure the width. It's just the first of several windows I need to work on. Just trying to get through the process on this.

Take a look at our S380-15 or S385-15. 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 will need a stamp option of 1420.
