Abstract
A concrete dispensing chute extension device for facilitating the pouring of concrete attaches to an end portion of a concrete truck chute and comprises a funnel-shaped lower opening having a cylindrical flexible chute extending directly downward. Concrete is poured down the chute and into the device, the device is directed straight downward into a concrete form. Utilization of the device reduces the impact of the concrete against the sides of the form and the incidents of the form capsizing.
