The spray gun is designed so that it can be adjusted to spray from a narrow to a wide pattern. The spray tip also can be changed without the need to evacuate contact adhesive from the spray hose. Mapebond 740 Spray Gun comes with a 6501 spray tip already installed. Alternate and replacement spray tips can be purchased from most industrial supply and paint distributors.
