Not sure what you mean by laterally across the board.
The bent hardware is perpendicular to the board.
Look at the 1st picture Hans posted of the hardware. The narrow base plate that has the 4 screws that mount directly to the snowboard were bent slightly. As I put pressure on the snowboard to get it to flex, I could see the base plate flex back and forth, there was about an 1/8 of an inch gap when it flexed back and forth. Not good.
I'm not trying to bash the SG plate system but wanted to point out some observations I noticed. If the hardware covered more surface area on the snowboard, I suspect this would eliminate the 1/8th flexing that was occurring.
