Autolock Pins are a safety device that is an important part of all ROGERS Ultima series goosenecks. The purpose of the Autolock Pins is to prevent the mating hooks on the gooseneck and the deck (beam hooks) from becoming disconnected when the trailer is in operation. The movement of the Autolock Pin in and out of position is done with a linkage connected to the gooseneck trapdoors. When properly positioned, the Autolock Pins rest in a notch in the interior surface of the gooseneck hooks. If the Autolock Pins do not properly position themselves in the notch it means the linkage has probably been bent and should be repaired or replaced.
