Abstract
A clamp member is provided with numerous lightening holes which comprise cavities and depressions formed on an inner surface of the clamp member. Bolt holes are provided through upper and lower surfaces of the clamp member and extend through the cavities. A reduced volume of the clamp member allows it to be manufactured from materials that are generally heavier than aluminum, but less susceptible to galvanic corrosion.
