Abstract
A concrete accessory for use with a ready mix chute comprises a funnel shaped hopper. The hopper has a wide upper opening of a size corresponding to that of a ready mix chute and tapering to a narrow lower opening. The hopper has a seamless inner surface and a pair of hollow aligned receptacles on opposite sides of the hopper and extending outwardly therefrom proximate the upper opening. An elongate rod has a length greater than the spacing between the aligned hollow receptacles to be received therein. A hanger assembly removably attaches the rod to a ready mix chute, in use, to support the hopper below the chute.
