This package offers everything needed for grain bin concrete applications in one convenient bundle. The beauty of this bundle is that crews can customize to just about any circular pour out there. The Center Pin Pivot replaces the handle of the screed. This simple invention has revolutionized the way contractors do circular pours by allowing the center to be adjusted to the desired height. The Center Pin Pivot also removes the need for a person to operate the non-motor side which helps with labor. Contractors are pouring longer pads with less workers.
