SpaceX lists the Falcon Heavy as weighing 3,125,735 lbs (presumably that's the "wet" weight). So, the hold down clamps 'only' need to deal with ~2,000,000 lbs

SpaceX lists the Falcon Heavy as weighing 3,125,735 lbs (presumably that's the "wet" weight). So, the hold down clamps 'only' need to deal with ~2,000,000 lbs of thrust. There are 6 clamps, IIRC, so that's 333k lbs each. Seems reasonable.
