Abstract: A painter's air hose guide has a flat web portion with oppositely facing surfaces and a rear side edge that is adapted to be wedged between the supporting surface for a vehicle wheel and its tire tread. A pair of flanges are symmetrically joined to the web portion so as to provide a contact surface for the air hose at the forefront of the guide structure and a ground contacting means for supporting the web in an inclined position regardless of which of the oppositely facing surfaces confronts the ground in a position assumed by the guide structure when it is dropped for insertion in its working position by foot movement of the worker.
