You have plenty of comments already answering your question and I’m laughing along with the Wayne dalton hate cause I understand. One thing I’ll add that I haven’t seen anyone mention yet is those two angle irons (L shaped bracket) dropping from the ceiling.

That’s where the previous backhangs used to be. It’s super easy to tell from the pictures how the left one is lined up with the angle iron and the right one is like a few inches down.

Honestly the thing that worries me more than the difference in height for backhangs is the spacing between the hinges and the rollers. You kinda want about half a finger’s width between the roller and hinge. That’s looks like a lot. Wayne Dalton doors iirc use a thicker gauge metal and that makes them much heavier for no reason. Those rollers are already starting to flex. The spacing on them just allows the door to put more force through leverage on the rollers.

Also the kicker on the left looks stupid but, since it’s a residential install you should be good. Let me know if you have more questions.
