Abstract: A dual reel hub assembly for coaxially mounting two independently rotatable confronting reels on an axially inward hub structure and an axially outward hub structure, respectively. The inward and outward hub structures are mounted on a common central spindle with the inward hub structure being freely rotatable while the outward hub structure is fixedly attached to the spindle and spaced from the inward hub structure. Each hub structure includes a reel support shell for supporting an inner surface of an axial opening in a reel. A plurality of radially outwardly extending key pins are aligned parallel to the spindle axis on each reel support shell to mate with one of a plurality of keyways on the inner surface of the axial reel opening. A rotatable locking ring on each hub structure is dimensioned to pass through the axial reel opening and has radially outwardly projecting locking fingers dimensioned to pass through the keyways and equal in number thereto.
