An improved adjustable hinge for a multi-position ladder that is positionable in a variety of configurations while being ergonomic to adjust and which is structurally sound, rigid, and easy to adjust, light in weight, and has a long service life. The mating surfaces of the outer hinge plates, inner hinge plates, and inner hinge center spacer are large, contributing to overall hinge rigidity and stability. The size of the lock button and lock bracket are each relatively large, making them ergonomic to operate, while also being large enough to be operable by a gloved human hand. A method of assembling an improved adjustable hinge for a multi-position ladder that is positionable in a variety of configurations.
