The Lastolite Kit BG Solo 3 m pivoting crossbar has a maximum width of 3 m but can be expanded to 5 m using an optional Lastolite Solo Background Support Extension.
A unique facet of this system is the pivoting crossbar that makes mounting and raising a roll of seamless paper or other backgrounds a one-person operation.
The system also includes two sturdy air-cushioned background stands and a carry case.
