The first rib tapers between a first thickness and a second thickness. The second rib extends from the surface of the tube. The second rib tapers between the first thickness and the second thickness. The channel has a first width between adjacent first thicknesses and a second width between adjacent second thicknesses. The first width is greater than the second width.
