HISTORY
MISSION STATEMENT
To produce state-of-the-art diagonally-strung tennis rackets utilizing proprietary technology. PowerAngle Rackets
have a unique, patented DIAGONAL STRINGING pattern which imparts unmatched CONTROLLED POWER
and spin. PowerAngle Rackets feature a BALANCED SWEET SPOT, due to diagonals being of equal length.
Scientific lab tests have proven that PowerAngle's diagonal pattern REDUCES VIBRATION by 40%. As a
result, our rackets protect your arm, elbow, wrist and hand from shock and undue stress. PowerAngle Rackets
are EASILY STRUNG and are LEGAL FOR TOURNAMENT PLAY. Our strings are angled for power, thus:
BACKGROUND
In the past, tennis rackets have traditionally been strung in a horizontal and vertical configuration. We are
forward-thinking tennis players who wanted a racket that would play better than conventionally-strung rackets.
Our goal was to explore a new frontier by changing the stringing, the only place where the racket hits the ball.
We formed PowerAngle LLC and designed diagonally-strung rackets along with PowerAngle clamps and string.
The revolutionary string that PowerAngle developed is half-black and half-white. This Duo-Color™ 17 gauge,
premium string changes color at mid-length, making diagonals in one direction black and opposite diagonals white.
PowerAngle Rackets reduce vibration by 40%, provide excellent playability and are simple to string. Our rackets
look different, play better and are healthier for a player's arm than any other racket on the market.
The PowerAngle Racket design was inspired by a prior racket invention patented by Madeline Hauptman. She
developed an innovative, three-directionally-strung racket based on the weave of a snowshoe. These rackets,
called "Mad Raq" (Madeline's Racquets), are on permanent display in both the Wimbledon Lawn Tennis
Museum in London, England and the Museum of the International Tennis Hall of Fame in Newport, Rhode Island.
Madeline Hauptman designed her three-directional racket because she enjoyed playing tennis, but, as an artist, her
precious painting arm was very sensitive to the vibrations she felt when playing with conventionally-strung rackets.
Madeline created the prototypes and it was proven that these revolutionary Mad Raq rackets significantly reduced
vibration transmitted to a player's arm, while simultaneously offering great playability. Madeline sold Mad Raq
tennis rackets and licensed her patent to several companies, selling more than 500,000 racquetball rackets and
10,000 tennis rackets with the Mad Raq stringing pattern.
However, Mad Raq's stringing pattern was too complicated for many stringers, because it required three sets of
strings (one vertical set interwoven with two opposite diagonal sets) instead of the conventional two sets of vertical
and horizontal strings.
In 2000, PowerAngle was created as the next generation of uniquely strung tennis rackets. PowerAngle Rackets,
featuring two sets of diagonal strings, are much easier to string than Mad Raq rackets were, yet still offer excellent
playability and ideal arm comfort. PowerAngle's equal-length diagonals disperse impact better than conventional
strings, which are unequal in length and vibrate at different frequencies.
