19 B. BSL




Hello! This balance looks very similar to our Series 350. Look it over and let me know if you agree; it comes with a 19-002 top and 15-004 bottom, so as long as those match you should be good to go. Based on your 19B stamp, you'll want a 20" balance and a 1920 stamp option.




It looks like you need the same S350-20 balances discussed in your original post form 2019 above. With that being said, it is strange that the balances from the same window have different stamps. I would recommend weighing your sash to determine the strength needed for your new balance springs. There is a chart on the product page that explains how to choose your option based on the sash weight. Thank you!
