If you are looking for this unit, then you know what you know what this does. This unit has been cleaned, lubricated and adjusted: restored to full working condition. Spent dozens of hours sourcing every missing screw and bolt and putting it back to working order. Modifies your Elinchrom heads into a fresnel type light. This unit comes with extra barn doors and a protective case. There are also cheap options for converting this elinchrom mount to a profit mount so that you can slide a b1/b10 head in there for the desired effect. One google search and you will find it. Great for cinematic portraits effects. This is only for local pick up in Los Angeles. I'm asking for $900
