I have a small double hung Andersen from the early 1980's.
The numbers on both balancers are the same.
B1 4 19 486
This goes against everything I've read in my searching for the right part?
The one in my hand is from the left side.
Your advice is appreciated,
Chris

Hello,

It looks like you would need the 24-431 Andersen sash balance for your repair based on the 4 19 stamped on your original assembly. Note that this balance is used for the left and right sides of the window. Take a look and thanks for posting!

Hello Casey,
Thank you so much for the information. I will be placing my order next week after I check another window that I have to do.
