Abstract
A ladder having a first ladder section, a second ladder section, an adjustable hinge mechanism, and an engagement indicator. The adjustable hinge mechanism is mounted with respect to the first ladder and the second ladder so that the adjustable hinge mechanism is moveable between an engaged position and a disengaged position. When in the engaged position, the adjustable hinge mechanism retains the first ladder section in a stationary orientation with respect to the second ladder section. When in the disengaged position, the adjustable hinge mechanism permits the first ladder section to pivot with respect to the second ladder section. The engagement indicator is mounted on the adjustable hinge mechanism. The engagement indicator is visible when the adjustable hinge mechanism is in the disengage position. The engagement indicator is not visible when the adjustable hinge mechanism is in the engaged position.
