In a second releasing position the jack lock may be easily and quicklyremoved from the jack. To further deter theft, a tongue arm is unitarily fabricated with
and extends from the jack enclosure. The tongue arm runs under a trailer ball receiver,and terminates with a hitch stop that wraps around the ball receiver to block a landvehicle from accessing the trailer coupler. A lock selectively holds the jack enclosureclosed to prevent the trailer jack from retracting, but when unlocked permits the jackenclosure to be removed from the trailer jack. Removal of the jack enclosure will alsoremove the hitch stop from blocking the ball receiver. A lock enclosure prevents accessto the locking mechanisms.
