Boy, had a hard time resizing it and changing the file name. Anyhow, they describe the installation as a 3G system in the text and show it as a 3G system but it is not.
Well, what I cal a 3G is not what http://www.valinge.se/products/1003127174/ calls theres. A 3G to me is the same as a 5G but without the pop-out plastic POS. It just drops down straight like a 5G and the next row locks down the end joint.
