Madeline Hauptman invented the MadRaq sometime in the 80’s I believe. You can see by the image the string pattern was unique and the basis of the patent granted to Ms. Hauptman.
You may have never seen a MadRaq and it is not your fault! MadRaq was up against many challenges the least of which was the string pattern! Diagonally strung racquets were not new but the introduction of the “third” string was. I have strung several of these racquets and they are a pain to string compared to standard string patterns. But, that pattern is what made the MadRaq such a delight to play with.
If you look closely at the pattern you can imagine that the strings would last forever since they simply did not move, which in turn did not cause friction, which is the major cause of string breakage.
The side of the racquet is printed with the following:
“Proved superior to conventional stringing in Weldon Laboratory tests by reducing vibration, enlarging power zone, increasing control and prolonging string life”.
MadRaq made available stringing clamps that were much like giant “C” clamps with rubber tips that kept the string from moving after tensioning. I have a set somewhere and will post an image when I find them.
