The Portable Background Support Kit from Bowens includes two stands, four crossbars and a canvas carry bag. Each of the stands has four height adjustable sections controlled by wing knobs. The overall height range of the stands ranges from 35.2" to 120.1". Three of the crossbars measure 41.7" and the other 38.2". They can interconnect in any combination via slots to accommodate a wider than standard size seamless or fabric backdrop. Both the stand and crossbars are aluminum alloy and transported in the included zippered canvas bag that has two carry handles.
