30" channel balance

I think our S385-30 can replace your balance. This comes with a 19-005 top and 15-004 bottom, so as long as those match up it should work well.

One important note is that stamps ending in "9" like yours are an outdated rating system. This means you'll need to weigh your sash on a scale and refer to the chart on the S385-30 store page to confirm the best match.
