    First of all a tornado does not care about the straps. And flange, yes straps will hold down a rtu 135 mph wind. However the mini tornado's that are spawned during a hurricane or any storm does not care about straps. Believe it or not tie downs are not required here.
    I did see a lot of them overturned here a couple of months ago after that wind storm.

    they aren't required here either, but the client needs them in order to continue their insurance policy. this is a large national company who has probably thousands of buildings to insure therefore they will do what they have to do.

    Yeah I would strap them to the curb. But, depending on the roof type,(is the roof built up on a concrete slab or corregated steel on red iron trusses)? We used to require the roofers to set the curb flange on the slab or corregate and shoot the proper faseners through the curb flanges and attach to the actual structure before building up around and flashing the curb. We were just trying to make our jobs as bulletproof as possible.

    If you strap them don’t bend the straps. It gives them play to move stretch.

    The last Rooftops we changed the tie down engineering was 300 4 and 6 inch tek screws through the base frame into the curb. If curb adapter? Then 300 adapt to curb 300 unit to adapter.

    We had ten units on that building. Screw cordless drills you got have a power drill to drive them. Also found you had to drill a pilot hole in the frame or the screw would not drill through the curb. PITA CITY.

    That makes Perfect sense. Because it does no good to attach something, to something that isn't secured itself!
