I should know this already...

On the rear roll-up doors of a semi trailer, are all slats the same height?

I've never had to measure one of them before, but now I need to know to scale a photo since I didn't get a measurement I needed... and all the trailers here currently are swing door trailers. (This is for a new 46ft Great Dane if that matters)
