ARB adjustable full hinge, fits door sections that are 18 to 24 inches tall. The adjustable slot lets you shift the hinge up or down a bit to dial in the alignment between sections. Includes four 5/16"-18 bolt nuts, a clevis pin, and a cotter ring. When your sections are not lining up right or you've got a gap between panels, an adjustable hinge can fix that without bending anything. Full hinge means it spans the full width of the section joint. Confirm your section height before ordering.
