This Rotalux Speedring from Elinchrom is designed to allow a 4 or 8 sided Rotalux softbox to be mounted on Profoto B1 an B2 OCF Flash Heads. Setup is fast and easy, and all guess work has been eliminated thanks to red marks that indicate the appropriate mount points for strip boxes: blue indicates mount points for square, and octas have no specific colour as they utilise all mount points. The speedring also features enhanced strength at specific points to ensure that any moveable parts will withstand the hard stresses caused by repeated assembly and disassembly.
