Window Balance; number stamped on channel is C 2545;

Question

This balance did not have any fittings attached on either ends.  The fitting that attaches the block and tackle to the spring has failed.  The number stamped on the back of the channel is #C 2545.  The actual length of the channel is 26 inches.  I need to replace both sides (2).

Hello,

Your balance resembles the S770-26 at first glance. The stamp code does not match our strength options, so you'll need to weigh your sash. There is a chart on the product page that explains how to choose your option based on the sash weight. Thanks for posting!
