As clearly shown in the accompanying pictures, the system consists of only a few large elements. The supplied screws are stowed in several small bags, so that a long search for the right screw for the right holes omitted.
The structure itself was relatively simple. A little help, the images in the product itself, which can be seen here at Amazon. A quick glance and I already knew what to do with which screw.
The entire structure, which is the way to create quite alone was done within 15 minutes. My three ARRI 800 watt spotlights with a total weight of about 40 kilograms could harm the crossbar. My fear that the traverse would bend under this weight is not confirmed. The Traverse was my weighing about 84 kilos withstand.
I can recommend this Traverse Light Craft Light stabilizer bar 100kg lifting capacity easily. The price is quite appropriate and therefore awarded 4 stars (1 star deduction for lack of assembly instructions).
