It's a thing on the door frame that holds the storm door on

This entire piece is 81 inches long. It screws onto the door frame and has 4 hinges that attach to the glass storm door. The top 2 hinges have broken. I bout 4 hinge sets of what I thought I needed and found out it was not correct. I have no idea what this long piece that I need is called to even try to locate it online. Your answer online just seem so helpful, I thought you might could help me. I have no idea what brand the door is and cannot find any markings. Do you have any ideas? I am not a quick learner at all but you do not have a category for "idiot that does not want to buy a whole new door"
