Abstract: A retaining wall block kit includes a block and an adjustable setback bar having a break line extending along a widthwise centerline between the front surface and the rear surface. The block has alignment knuckles protruding downwardly from a bottom surface of a front section, and has a receiver channel extending laterally across a top surface of the front section for receiving the alignment knuckles of an adjacent upper block. The setback bar can be removably located within the receiver channel, and is configured to be split along the break line. Thus, the setback bar is adjustable by being modified or omitted altogether to change the distance between the alignment knuckles and a front surface of the receiver channel and thereby allow the setback of the retaining wall to be changed as desired.

Abstract: An apparatus for manufacturing a molded item having a corner is provided. The apparatus includes a mold support for holding an angled mold having an inside corner. A hopper having an outside corner that corresponds to the inside corner of the mold and a screen at the outside corner mates with the mold. A vibration device is provided for causing a material contained in the hopper to pass through the screen, such as by applying a predetermined force for a predetermined period of time required to fill the mold. Different sized openings in the screen combined with the flowability of the material and the amount of vibration can determine how much material flows through the screen.
