I'll say something that no one seems to ever mention.
The further you get to the ends of the extruded channels the more flex/give there is.
So basically if you are putting a cleat right on the end of the extrusion it will pull more than if you put a cleat in the middle of an extrusion.
Found this out hauling 1,100lbs of hardwood flooring.
I cranked the ratchet straps down about as tight as I could get them and I could see the extrusions on the floor of the bed bowing up.
Everything held for my 1 hour plus trip, but it had me slightly concerned so I drove like it wasn't even strapped down just in case.
Moral of the story is for maximum strength locate cleats right where the extrusions bolt to the bed.
