Abstract
The present invention relates to a ramp system. The ramp system includes a riser component that includes a first side and a second side that meets the first side. The second side and first side form an angle that is less than 90.degree.. The ramp system also includes an adjuster component positionable within the riser component. The adjuster component lifts one end of the first side so that an angle that the second side makes with the horizontal is increased when compared to an angle made between the second side and the horizontal without the adjuster component.
