The support width is a milled slot on the rear side of the
tube, which is necessary for = mounting to the handle system (wall system,
etc.). This milled slot is available in the so-called “short width” (length of
tube 30-180 cm) or “long width” (length of tube 120-300 cm). Your decision
should be based on the desired lengths. Prices of both systems are identical.
