ABSTRACT:
An anti-rattle, locking hitch receiver clamp has a lever arm, a hand screw at one end thereof, a force plate at an end opposite the hand screw, and a pivot located therebetween, but closer to the active edge. The clamp may be slipped onto a first shank such as a trailer ball shank, and then the first shank inserted into a hollow receiver such as a trailer hitch receiver. The hand screw is then rotated and, through the pivot, the clamp applies a multiplied force between the shank and receiver. The clamp will then securely retain the shank within the receiver without rattle or vibration therebetween. A trailer hitch pin may be used for the pivot, though other variations of design and materials are disclosed.
