Would like to replace Anderson sash balancer from a window installed around 1986 or 1987.  The stamp I see is  E41 9#27 6 86 .  Which one would I use as a replacement? Thanks.

Hello! Based on your stamp of "9#27" then my top recommendation is the 24-939. This is specifically designed to replace Andersen balances with that marking.

Please let me know if you had any other questions and I would be happy to assist.
