There are two models of tubing to select from. One being just plain tubing, the other being swaged tube. The plain tubing is in lengths of 1000mm, 1500mm, 1900mm and 2900mm. The swaged tubing is crimped on one end, enabling it to be linked into an open ended tube, ideal for when creating longer expanses of continual railing. Also sold in the same sized lengths. For the swaged tubing, a dress ring is supplied to cover any cut or joining piece. This makes it safer for the end user, as well as enhancing the appearance of the rail.
