A handle attachment for mounting to a standardized valve mounting cup of a spray can and operating a push-type dispenser valve. The handle attachment includes a housing that defines a grip and a cap configured to couple with an outer diameter of the valve mounting cup. An actuation device is pivotally mounted to the housing and includes a trigger portion disposed adjacent the grip and a finger portion disposed within the cap for actuating the push-type dispenser valve. A C-shaped rim is disposed on the cap and defines a central opening sized to accommodate the valve mounting cup, a base located on the axis of symmetry of the rim, a circumferential gap located on the axis of symmetry diametrically opposite the base and separating two ends of the rim, and at least one slot disposed between the base and a diametrical chord perpendicular to the axis of symmetry.
