This socket (really great !!!!) is screwed in a clay soil (especially not in cement) to be able to fix then solidly big umbrella dryer of the same brand Leifheit 82000 rotary clothes dryer 40m that comes only with a socket for cement. Not wanting to break the soil to leave "for life Eternam" planted a bush in the garden cemented courtyard, I much prefer this one to sink into soft ground. Given its width and length, it is clear that it is not likely to move, but it takes a grip to be able to install even comes with the metal bar to be able to rotate. (So rather to be determined by a man because a woman is really too difficult).
Arrived the day after the order, I am very satisfied with this extremely solid product. Good value for money.
