Abstract: A loading dock bumper assembly includes at least one bracket for mounting the assembly on a surface of a loading dock. At least one resilient bumper component is attached to the bracket, the bumper component formed of a block of resilient recycled plastic material is positioned to receive the impact of a motor vehicle backed into abutment with the dock. The block is preferably formed of extruded high density polyethylene. A side of the block adapted to receive contact with a motor vehicle may be provided with a slot along its length. The slot is adapted to have secured therein a wear bar substantially of equal length with the bumper component. The preferred wear bar is a steel bar of rectangular cross section fitted into the slot with a surface thereof substantially flush with the surface of the resilient component. At least one corner of the block preferably is provided with a chamfer cut at approximately 45.degree. whereby lodging of a truck bumper on the assembly is obviated.
