After I've read that some buyers have this ground socket used for a purpose other but successful as a holder for a flagpole, I made the decision to try it also times with the sleeve. I had a problem with the mounting of a banister to my garden outside staircase. One of the stand of the handrail was not so fit as I had planned it. Now came the sleeve. used. Easily they could be screwed into the grass (heavy clay soil). Stand in, tighten and be amazed: the thing is stuck (see how long times). Am thrilled !!
