If you have another manufacturer's shaft/mounting kit and want to use our beam and receiver block with that aparatus; and the shaft you are dealing with is 1.25" or 1.5" inches in diameter then you are in luck.  You can use this split clamp to convert your current Gen3 Pole and beam system to a set up as such.
