ABSTRACT:
The loadlock and beam of the present invention are for use with a pallet rack structure in which the beam is connected to an upright of an end frame with the loadlock. The loadlock has a right angled-shaped bolt with a shank slidably extending through an aligned hole in the upright and in an end plate of the beam and has a headed handle portion extending through a contoured slot in the beam wall adjacent the end of the beam. The contoured slot defines three separate positions and cooperates with a generally cylindrical spring metal retainer positioned on the bolt handle having diametrically opposed projecting tabs engaging the innerface of the beam wall adjacent the slot and having projections engageable with the edges of the contoured slot to position the loadlock in any one of the three preselected positions. The slot and the loadlock cooperate to prevent manual movement of the lock between the shipping and locking positions, thereby preventing inadvertent disengagement of the shank from the upright and beam end plate.
