Abstract
Abstract An improved cornerboard for a pallet is provided wherein conventional boards are equipped with top and bottom caps which may be fabricated of a suitable hard material such as plastic or metal. The cornerboard caps of the present invention protect the ends of the cornerboards from damage and also hold them in the correct right angle alignment. Cornerboard caps may be fitted with top portions which further protect material on a pallet. In accordance with one embodiment of the invention, filler sections may be employed so that a given set of cornerboards can accept loads of different heights.
