Abstract: An adapter for coupling a straight inner beam and a curved outer beam is provided. The adapter includes a u-shaped body, inner snap pins, and outer snap pins. The u-shaped body includes a horizontal side and vertical sides forming a channel mating with the inner beam at an interior side of the u-shaped body, and mating with the outer beam at an exterior side of the u-shaped body. At least one of the inner snap pins is arranged on an interior face of each vertical side. Each inner snap pin engages with one of the inner pin such that the u-shaped body is secured to the inner beam. At least one of the outer snap pins is arranged on an exterior face of each vertical side. Each outer snap pin engages with one of the outer pin holes such that the u-shaped body is secured to the outer beam.

Abstract: A tonneau cover frame for use with a bed of a pickup truck. The frame including a plurality of side rails, a plurality of end rails and a plurality of cross rails. The side rails being configured for extending along sides of the bed of the pickup truck, the end rails extending between the side rails adjacent to front and rear ends of the frame, and the cross rails extending between the side rails at a location between the front and rear ends of the frame. The plurality of end rails and the plurality of cross rails each having an adjustable length, whereby the frame is adjustable in width for use in connection with differently sized beds of different pickup trucks.
