## Abstract

A protector allows for the engagement and protection of a segment of an upright from an impact force by an external object and for absorbing and damping the resulting impact force. The protector comprises a protector body and a shim. The protector body allows engagement and positioning of the protector on at least a segment of the upright. The protector body is also partially constructed of an energy absorbing and damping material and having an outer surface and an inner surface. The outer surface is positionable to receive the impact force from the external object. The inner surface is positionable to abut the upright, when the protector is in engagement with the upright. The shim is least partially embedded in the protector body and provides increased structural support for the protector body. The shim also has a stiffness different than the stiffness of the protector body.
