    Abstract: A ground engaging tip of a ground engaging tip assembly includes an adapter that attaches to the base edge and having a forwardly extending adapter nose, and a ground engaging tip. The tip has a rear edge and a top and bottom outer surfaces. The top and bottom outer surfaces extend forward from the rear edge of the ground engaging tip and converge at a front edge of the tip. The tip includes first and second side outer surfaces extending forward from the rear edge to the front edge. Tip includes a nose cavity for receiving the adapter nose therein. The nose cavity has first and second side inner surfaces opposite the first and second side outer surfaces, respectively. The nose cavity has an aperture and a retention channel on at least one of the first and second side inner surfaces. The retention channel extends from the rear edge to the aperture and guides a lug of the adapter into the aperture during installation of the ground engaging tip on the adapter. The retention channel has an untapered portion and a tapered portion, with the tapered portion extending from the rear edge to the untapered portion and the untapered portion extending from the tapered portion to the aperture.

    Abstract: A ground engaging tip of a ground engaging tip assembly includes an adapter configured for attachment to the base edge of the implement and having a forwardly extending adapter nose. The ground engaging tip has a rear edge, a top outer surface, and a bottom outer surface. The top and bottom outer surfaces extend forward from the rear edge and converge at a front edge of the ground engaging tip. The tip has first and second side outer surfaces extending forward from the rear edge of the ground engaging tip to the front edge. The tip has a nose cavity for receiving the adapter nose therein. The tip has a support rib on at least one of the first or second side outer surfaces, the support rib being positioned at the rear edge and extending lengthwise from the bottom outer surface toward the top outer surface.
