The structure is quickly and easily possible. You have to pay pipes together and fasten them using a wrench (which is not included) is required. The instructions are clearly understood and clearly. The first frame I needed about 15 minutes, the second just under 10 minutes and I'm an office man.
After assembling the stacking aid acts sufficiently stable and can be unloaded easily moved by one person. A subsequent change in width in various detents (not stepless). For four screws need to be resolved, are pushed together the pipe and re-bolted.
For me, the stacking aids on pavement under carport are "leaning" on a wall (enough spacing for ventilation is available). There they are very stable and do not wobble. By constructing a ventilation is provided from below and at least on solid ground. On a soft ground I had some concern whether the stacking aid will not sink.
For a stacking aid I had brought me a cubic meters tailored oak from a sawmill. The amount of wood fitted almost exactly into the stacking aid. When stacking one has indeed to think that down and lie on the sides matching pieces of wood, but otherwise no problem.
In the second stacking means I have stacked a little overgrown and poor split wood from the garden of my father. Here the layers also was complicated but possible. I have been there easily overloaded the stacking aid. You should / may only be loaded to the brim of the bracket. I have stacked the last position it and thereby realized that the bail slightly but visibly tilts outwards. But he keeps.
For durability, I can still make a statement and with me the stacking aids are also very protected.
If I had more space I would have a third pick me, but then the car would no longer fit into the carport.
