A versatile manually operated striping device has a wheeled base and a handle for pushing the base. The base is in a block Y configuration which provide a U-shaped front end. The front wheels are mounted on separate axles that are extra long. A disk shaped mask is attached to the inboard side of each axle. For normal striping, a can tower is mounted on a moveable mounting bracket that is positioned so that the center of the bottom of the can tower is centrally located in said U-shaped front end. An aerosol spray can inserted in the can tower then sprays, the paint between the legs of the U to provide the normal working, when an actuator is activated. The moveable mounting bracket can be relocated to permit spraying behind the central transverse portion of the base or to the side. The mounting bracket includes a pluralty of holes in a vertical line that fit mounting studs that are attached to one side and to the rear of the can tower. The height of can tower, and then the height of the aerosol spray can is a measure of the spray width. Calibration marks may be located adjacent the holes to denote spray width. The disk masks may be positioned to provide a clean edge by adjusting the position of the axles, and should be coordinated with the spray height to obtain the best results.
