I had a broom in my vehicle and used it to prop against the octa to prevent turning. I tightened the set screw on the cheetah strobe as tight as I could but it did not help. Looking for a better option of how to prevent this?Photos?

Even in that role, the screw idea is pretty screwy, and baby pins with a bevel only stress the screw further. To entirely eliminate torque on the screw by gusting from any direction, including vertically, mount the light inline with the baby pin. This is possible with the grip arm and a baby-pin adapter (to be held by the knuckle). Rotational torque generated by the wind will now be resisted by the riser clamps—an easy matter unless you are using crappy alu stands.  Canon, Nikon, Contax, Leica, Sony, Profoto.

Just got to my studio, so here's a better example:  Again, baby pin and head are inline. You can survive with grip head alone but, with the grip arm, you gain some distance from the stand for downward angles (important for big modifiers as key). Angle adjustments can be made on either knuckle without affecting wind resistance. Of course, the whole rig blowing over is a different problem.  Canon, Nikon, Contax, Leica, Sony, Profoto.
