German lines, or lines without nails, are a viable alternative to classic lines with nails and offer countless advantages. In both cases, the following are essential: proper maintenance, since being made of plastic material they tend to expand over time, and that the laying is done on a stable, well-rolled court.

As a company we offerthe service of supplying and laying German sockets, boasting years of experience in the court.


The main advantages leaving aside the aesthetic beauty are many:

  • They have a longer life span since they are made of a stiffer and thicker material. If properly maintained they can be replaced every 20/25 years, in this period only the bottom line of the court is changed as it is the one most subject to wear from footfall;
  • They can be removed and repositioned whenever there is a need without being throw away;
  • The installation and removal are easier and faster, normally two people take 2 1/2 hours for the first one and 30 minutes for the second one;
  • Better court flatness, precisely because during maintenance they can be removed and there is no need to go around them;
  • Better regularity of play due to the different bounce of the ball, not presenting the irregularities given by the presence of nails.


Lines with nails have the one advantage that they can be repaired with nails and a hammer. This means that in case there is a need to add a piece of line it would be sufficient to nail it, while in the case of German line 2 additional sockets must be inserted into the ground so as not to lose the correct tension of the line.

If, on the other hand, in cases like this one does not want to use additional bushings, very strong clamps can be used to “stitch” the two ends of the scale; a less aesthetic but equally good solution.


The first laying, but also the subsequent ones, should be done when the court is practicable and level, thus at the end of maintenance, possibly with damp soil to facilitate the work.

To begin, one must square the court and find the four corners that delimit the playing area. After taking all the basic measurements one begins to lay the 18 compasses needed, one at each end of the lines.

Once the sockets have been buried with the appropriate tool, the lines must be tensioned and secured with an L-shaped or T-shaped locking bracket inserted into a socket.


German lines, depending on the type, can be already made to size or to be cut, specifically:

  • Specialty Rows: they are not made to size but are sold in total sets consisting of a 30-meter piece from which to make the center and service lines, a 22-meter piece for the end lines, and 25-meter pieces for the others;
  • Geniala sockets: they are already cut to size;
  • Court plus lines: these are already cut to size, but the difference with the Geniala lines is the thickness, all the lines are 4 cm except for the end lines which are 5 cm because they are subject to more wear and tear.
