Thanks for posting! This resembles our S395-28 channel balance. Look it over and see if you agree. 27 9 is not a standard stamp, so you will need to get the weight of your sash and compare that to the chart we show on the S395-28 store page. That is the best way to determine which of our options is best.

Thanks for the quick response, sash weighs 30 pounds so will get 2760 series.
