Flatbed Headache Rack

Many different issues. Kingpin setting on trailer that determines how much the front of the trailer sticks out on a turn. A 36 inch kingpin takes about 54 inches for the corner of the trailer to clear when turning. How large is the sleeper? Do you have to load the front axle to 12,000 lbs? On a double sleeper truck-tractor, I think you should have at least 244" wheelbase, but each situation is different. I have seen headache racks that bolt to the side of the frame rails instead of having a support u-bolted to the top of the frame rails.

We've always run the racks on the trailers. The law in TX changed not too long ago and now we do not add racks to trailers any more. In Texas the law is written as securement and as long as you have two straps within 5' of each other on the front your golden. Only need one strap if the load is in contact with the rack. So even with a truck mounted rack you still need two straps on the front within 5' of each other. Law might be different in other areas so check first.

We haul primarily pipe and rebar on flatbed. No difference between the two. Two straps within 5' of each other in the front and then every 10' after.
