"And if I ever went to court I would set up a demonstration were by the door would reverse with a 2X4 in the center but not 2' from the sides. Then I would put a kids bike with a big doll as a rider on the bike. I would then push the button and as the door crushes the doll and the bike, the defense rests." I am curious as to how you would accomplish this. Not saying that you couldnt, but I am curious. Standards are not intended to be comprehensive. They are developed considering historical data (failure modes), design data, practicallity, trial and error, and ability to be documented, among other considerations. These standards were not pulled out of someones arse. They were developed by engineers taking into account design variables among different manufacturers, variables considering improper installations, variables considering differences in materials, etc. An inspector who relied on feel in the face of a documentable procedure would be eviscerated on the stand IMO. If an inspector trusts his 'feel' over all else, by all means use your hands for self edification, but sliding the 2x under the door as well and testing to procedure would be an easy way to CYA. Tim
