Here at Fulkrum we have taken an old idea and by todays technology and our innovative engineering staff, we have came up with what we think is one of the most sought after inventions of its kind. We hope you enjoy not only its shear strength, but its simplicity. The trailer hitch of yesterday has now evolved into what we call is here at Fulkrum a Self Coupling Hitch. Yes, it's just that! Self Coupling! Open Fulkrums hinged cuff block your trailers wheels and simply back your vehicle into the trailer tongue. The tongue pushes the cuff to the closed position, pivoting the ball into the coupler and CLICK! Your ready to go! To unhook scotch your trailers wheels, set your jack just till it touches the ground. Disengage the safety latch and pull away.
