It's really not hard to sling a cooler to keep it secure--whether on the trailer or to prevent its loss in a flip.
All the variations people use are to keep the cooler from rotating when someone sits on it or steps on it. The NRS corners really just keep the cooler from rotating/sliding on the lower sling straps.
I've been told that these do the same thing as the NRS ones. They are used in the trucking industry to protect the corners on loads that are strapped down. You can sometimes get them in truck stops.

That's a brilliant idea. I really never liked the NRS corners because while they work, they're an extra sharp edge down by my toes, and they turn the floor black. Lately, I've been using a drop bag to sling my 90qt Igloo cooler for day trips. The PVC-coated mesh is grabby enough that the cooler doesn't really rotate.
My larger 105qt Canyon cooler has a lip that sits on the front and back rails.
ebh0619, yes, a pair of 10' strap with strap slides at the front and rear bars would do the same thing as a pair of 6' loop straps on the bottom, and 4' loops on top. You will have to fiddle with it to get the length on the bottom just right, but you'd do the same thing by adjusting the 6' loop strap lower sling.
Maybe some PlastiDip or Aquaseal painted on the lower straps would be grabby enough that corners are not needed?
