E50 9#27 10-77 Andersen Balance

Looking to replace both the right and left sash balancers on my Andersoen narroline double hung windows that measure about 53"X 36". The balancer on the left has the following numbers:
E50 9#27 10-77
I am guessing the 10-77 is the date of manufacture since that is about when the house was built.
Please advise which Swisco balancers are needed.
Thank you.

Hello,

Based on the 9#27 stamp shown in your photos, the correct Andersen sash balance for your window would be the 24-939. Take a look and thanks for posting.

Paul, does that mean order 2 of the 24-939 balancers because I dont see anything in the numbers that identify a left or right balance. Are the good for either side?

Correct, the 24-939 is a non-handed balance assembly that installs on the left and right sides of the window header. Thank you.
