E63 9#27 .7.87 Andersen window sash balancer

Question

Hi,

I'm trying to repair an old Andersen window where the slash is bad.

It appears to me the part numbers are 11600-17.

I also see a number stamped on both balancers:
E63 9#27 .7.87

I recommend our 24-939. This can replace all Andersen operators marked with "9#27," like your original.
