I have just come out of the basement, where I've built the shelf. At first I was a little disappointed, because after opening the package no guidance was to be found. But it also does not need. First of all four lower spar parts - angle profiles each with a hot shoe made of plastic. A long connector plug and in the height of the lower shelf with the engaging noses in tabs of the two bars or legs - two of the bars on the wall Lean - these are, so to speak, the hind legs. Before any turn with pliers lying in the sheet plane noses up a little so that they can easily engage in both tabs. Then possibly with a hammer to cross connectors a little deeper. As is ever the back. Then include just a short connector another, front spar as the third leg, then is the shelf before on three legs. So you need to build no helper. What happens next, even as the shelf is soon realized solely with the lower spar half results in a workbench. A very small number of form elements results in an ingeniously simple - and thus, of course, cost-effective design and virtually eliminates that you're doing something wrong. Anyway, I'm a scribbler with little calluses on the hands, have nevertheless taken no gloves and am also not hurt. Of course it is not a "nice" kitchen shelf. But absolutely for basements, garages, etc., to my knowledge TOP. Gladly I would also six stars.
