Out-to-Out Main Beams is the measurement of the width between the outer edges of the top main beam flanges on the deck of a ROGERS trailer. This dimension is especially important in the design of
drop side deck and
I-beam deck trailers to ensure that machines to be loaded on the deck are able to straddle the width of the main beams.
