A pallet rack system has a safety lock on end connectors of horizontal beam members to prevent accidental removal of the horizontal beams from the vertical frame supports. The safety lock includes a cross-shaped member rigidly secured to the beam connectors and a U-shaped member associated with the cross-shaped member to operatively couple the U-shaped member with the end connector. The U-shaped member includes a hook which cooperates with an aperture in the frame supports to lock the safety lock device to the frame support which, in turn, locks the horizontal beams with the vertical frame supports. |
