I had to have me appointed this ground socket to a suitable for Wäschespinne same manufacturer. Trying to get them in the ground failed because the sleeve burst into two parts.

The material of the rod (5 Stars) bears no relation to the quality and durability of the ground peg. Even plastic tabs on the cover mechanism broke even at first dry runs in the warm room.
