Millard window balancer

A home owner from Lake Tahoe, CA says:
The balancer is 33" long, has a 32c stamped on it and is the 9/16" wide. I recently purchased 2 that were wrong on order "797666 using the search of 32c

Thanks for posting. 32C isn't used in identification, unfortunately. It only tells you how strong the spring is. The Series is based only on the style and measurements of the nylon caps on either end. In your case, I think you could have either our S380-33 or S385-33, depending on the size of the bottom shoe (first picture). That is the only difference. You will need to measure your own shoe to confirm which is better.
