Re: Fasteners extending outside the FRAME PERIMETER

But at least teams have time to fix it.

I honestly have no dog in this hunt as the robot our team is building meets the rule without even the fastener head exemption in the bumber zone* but I am really glad that this was addressed soon and clearly.

Well done GDC.

*this being the first year back in the game in a while and therefor not poluted with prior year's rulings, I read the rules and thought they were pretty clear. So... I used C channel facing outward for both the bumper mount structure and the robot chassis. As noted above, it leaves plenty of room for screw heads. Recommended.
