Abstract
A wedge connector for securing the horizontal cross beams of a storage rack to the hollow upright posts of the system. Two ear-supporting members extend laterally from an elongated shank, each of which members carries an upwardly extending welding ear. The wedge connector has a shape and carefully controlled dimensions that make it possible to insert the elongated shank and upper wedging ear into the lower slot of a pair of elongated slots in the upright post of the storage rack. The elongated shank is then pivoted up within the interior of the hollow post into a position where the upper wedging ear can be moved back out of the upper elongated slot of the pair of slots, to place the wedge connector in its operative position. The dimensions of the lower wedging ear of the wedge connector are controlled so that the lower ear can not be inserted in the lower elongated slot in the upright post. The features described produce the advantage of being able to insert the wedge connector from outside a hollow, completely enclosed tubular upright post, while at the same time retaining the advantage of locating the elongated shank on the inside of the post when the connector has been placed in its final operative position.
