  • Patent number: 6948733
    Abstract: A trailer hitch alignment device facilitates the alignment of the trailer tongue with the drop hitch ball of the towing vehicle. The device includes a vertical back plate, curved in the middle to create an obtuse angle to partially surround a drop hitch ball in order to guide the tongue of a trailer toward the ball hitch. A horizontal base plate is attached at a 90 degree angle at a height above the bottom edge of the vertical back plate. An aperture in the horizontal base plate allows for the emerging ball of the hitch. The invention is held in proper orientation by a snug, tight fit between the hitch post and base plate and/or back plate to prevent displacement during use of the invention.
