The base plate is relatively high, the holes for the anchors are wide. So the hook forgive small weaknesses when drilling the holes in the ceiling, even if they are wrong, the hook can still attach. But beware, although you have to work very closely. For me it was at the end of a precision job, I'm just not a craftsman, neither professionally nor privately. When fastening way, I have the holes again somewhat "purified" with the 8-drills, then over it then reingesteckt with a vacuum cleaner the plugs. The dowels have still not quite fit into the 8- holes, I had it all purely with the hammer (I hope that now reads not enraged craftsmen and told me directly that this was not so smart x D).
Once you sit in it during suspended chair, you feel very safe. Stirs nothing on the plate. The hook also makes no noise, neither the turn nor while swinging. Only in the application, I realized how useful it is to use a hook that can rotate. The rope does not get tangled up in the least and rotates very smoothly. Great!
Incidentally, I have attached the hammock chair on the balcony. The landlord said it was ok, the balcony is only 4 years old and is made entirely of a balcony, though it has only once a strange feeling to be drilled in such a free-hanging plate over his head holes pure. I do not know if I'm too sensitive there, or my concern is even attached and my landlord has no idea. The concrete slab is about 12 cm thick. At this point, the urgent recommendation: please do not use a 50 drill trying to drill holes in a massive concrete slab. The games we have operated and were after about 45 minutes in a hole 4 cm wide. I am then off to Werkezugverleih and I've borrowed a drifter who comes from the brand with the 250 and were within 15 minutes every 4 holes buttery soft finish, including balanced pause between each Bohrlauch: D
