Andersen 837 Narroline Sash Balancer

The original balancer failed after 25 years. Searched and found out what I needed and how to replace it. Ordered and had it in 2 days. Followed the instructions to install it and its like brand new.

This and YouTube made the replacement job pretty easy.

Very good quality. Easier to install with a little help, but can be a one man job. Looks like original equipment from Andersen.

Window is repaired. Best to use the Anderson site to make the right selection and instructions in taking window apart. This one was most helpful for me: [...]

Expensive
