Help finding the right window channel balance

A quick learner from Portland says:
The only marking on it says "27 4 FX Caldwell. It is 28" long and 1/2" wide. Thanks for your help.

Sure! We're always happy to help. Based on your pictures, I would recommend our S385-28 channel balance with a 2740 option. Please review this hardware and let me know what you think.
