A mounting clamp and assembly in which the clamp's intermediate web extends across the support member at an oblique angle. A pair of side rails are adjustably coupled to the support boom, each side rail having a separate clamp for independent adjustment with the side rails being diametrically opposed. Each clamp has a raised contact surface on one side to permit the clamp to remain fixed on the support boom while the side rail is adjusted.
