Abstract: A unique corner bumper for use on movable objects and particularly on movable vehicles, such as trucks and truck trailers, to protect a fixed or stationary object, such as a building or other rigid structure, against the force of an impact by the movable object. The corner bumper has a pair of elongate sections integrally connected together at common ends and which elongate sections have generally perpendicularly arranged interiorly presented surfaces and an upper interiorly presented surface of a top wall which is also perpendicularly disposed to the interiorly presented surfaces of the side walls. In this way, the bumper will fit over an upper or lower corner portion of a truck trailer, for example.
