US Patent 10195639 Modular spray roller system

A spray roller system for application of architectural paints coating, includes an extension tube, a spray head mounted on a distal end of the extension tube, and the in-line valve with a trigger mounted on a proximal end of the extension tube, and a roller handle removable mounted on the extension tube adjacent the spray head. The spray roller system can spray and back roll a coating on a down stroke and roll on each up stroke. When the roller handle is removed from the extension tube, it can be used to hand roll sensitive wall areas. With the roller handle removed, extension tube, spray head, and in-line valve can be used as a spray extension to apply coatings in hard to reach areas.
