A tool container assembly includes a container, rollers, a handle, and a slidable closure member. The container includes an upper and a lower storage space therein, a rear wall, opposing side walls, a lower front wall and a front opening above the lower front wall. The front opening generally lies along a plane that extends away from the rear wall as it extends downwardly. The slidable closure member is slidably movable between a first position wherein it substantially covers the front opening and a second position wherein it exposes the front opening. The closure member moves to a position wherein it generally lies between the plane and the lower front wall, and at an angle with respect to the plane, when it is moved to the second position.
