Garage Door Opener Rails

I recently replaced my 30 year old Craftsman opener with a new model chain drive. The new opener has a 4-piece ceiling rail and it flexes downward slightly when the door opens. Is this normal?

that is normal. this mostly happens when the opener is just starting to open the door and the opener is not pulling the door up as much as it is pulling the door back. one thing that can be done to help is to make the arm that goes from the door to the opener as straight up as possible when the door is fully closed.
