This is a demonstration of the High Sierra Antenna "Jaws" clamp in action. It not only clamps on to wood, but to metal and anything else which is 2 1/2 inches in width or less. It is advertised as 2 inches in width, but I was able to slightly open it up more. So now I know what is possible should the need arise. Photo taken on Sat, November 27, 2010
