A safety and restraint assembly allows transition of palletized cargo into a cargo bay and prevents the palletized cargo from inadvertently rolling backwards out through the cargo bay door. The assembly includes a wedge-shaped, spring-loaded, anti-rollout component that rotates downward as force from a pallet is applied to the anti-rollout component during loading of pallets, and the anti-rollout component returns to its original position after the pallet has traversed entirely over the anti-rollout component. The assembly also includes a folding restraint pawl for vertical restraint of adjacent pallets during transport. In an engaged position, the restraint pawl snaps into a slot in the anti-rollout component.
