An improved payout tube adapted to be secured to a container having wire or cable contained therein, has a flange at the entrance end thereof. The flange has a radiused surface wherein the radius is greater than the critical or kinking radius Rc, and a central opening where the radiused surface fairs into the inner wall of the tube, with the inner wall being substantially tangential to the radiused surface. A plurality of strengthening ribs are located on the underside of the flange and extend along the outer wall of the tube, with certain ones of the ribs intersecting other ribs at right angles thereto. Mounting means located at the exit end of the tube also has strengthening ribs, with strengthening members intersecting the ribs at right angles thereto.
