Our largest light stand, we have aluminum and steel versions.  These have 4 stages, with a receiver for 1 ⅛” studs, as well as a retractable ⅝” pin (hence the title combi).  These are used for fixtures like our 1200 HMIs, or to hold 8′ x 8′ frames using lollipops.  Fully extended it gets up to 177 inches and has close to a 4 foot base.
