Al,
Could you give guidance on a mounting system like this, mainly the part in red:

The green parts are our robot / frame perimeter, everything else is BUMPER. We have used the wing nut/stud method before so I am not worried about that. My main concern is the (red) aluminum 2.5x1 angle that rises above the top of the bumper. Everything remains in the 2-10in bumper zone, but I have never seen an attachment method that went above the bumper itself in recent years. I can't find a rule this would violate and our own LRI, Brian Lucas, says it's fine, but this really seems like it's pushing it. I just wanted to get a second opinion before we start cutting metal.
Thanks.
