I am looking for the equivalent to a 25-9 window sash balance. It looks like I have a Series 385 by the measurements as the bottom plastic measures 1 3/32"(actually closer to 1 1/16") but having a hard time comparing weight. Do you know what the equivalent weight rating is for a 25-9?

Hello,

Your 25-9 stamp is actually from an outdated weight system that is no longer used. I would recommend weighing your window sash and following the chart on the S385-26 product page, whcih explains how to choose your option based on the sash weight. Take a look and thanks for posting!

I appreciate the response, thank you for checking on the old stamp #, I'll check the sash weight before purchasing!
