A shipping crate formed from connected V-shaped corner board sections. The shipping crate includes top and bottom frames each formed from sections of corner board. A series of attachment clips are used to connect the top and bottom frames to corner uprights and one or more cross supports, where the corner uprights and cross supports are formed from sections of corner board. The attachment clip includes a center wall and front and back walls that each combine with the center wall to form first and second receiving cavities. The first and second receiving cavities are each able to receive one leg of a corner board section. A guard wall is formed on the attachment clip and spaced from the back wall to define a connector cavity. The connector cavity receives ends of a series of connectors used to join the corner board sections within the attachment clip.
