Abstract
An overhead dual arm tubular structure for supplying fresh and/or pneumatic air power to an operator and/or his air tool in a work area of varying shape. A structure whose main arm is freely revolvable about its vertical axis has a second arm of similar length swinging radially from its free end. Self returning hoses carrying air down from the second arm's outward end, enable an operator to work high or low anywhere within the periphery of the dual arm radius. A belt clip hanging at the end of the self returning hoses incorporates a quick release mechanism and hose swivels to allow the operator to easily engage and disengage from his fresh air supply and revolve freely about the attached fresh and/or compressed air hoses without risk of entanglement.
