Local Inventor helps level the playing field at U.S. Open

KNOXVILLE, Tenn. (WVLT).-- It's the little things in life and sports that can make all of the difference and one local man is using a little thing to make a difference at the U.S. Open.

The TNT Gauge is the brainchild of Knoxville resident David Glass. According to Glass, it removes the last variable from tennis courts by indicating the tension on the tennis net.

The gauge now allows all tennis courts at a particular event to play the same way, which makes a big difference to the pros.

"It creates a consistency that they can expect from court to court," said Glass. "The competitive players all expect the court to be predictable."

The University of Tennessee was a guinea pig for the project, allowing Glass to test his product on their courts.

"The first competitive matches that it was used in dual matches here. And then the NCAA Regionals that were played here in May of 2011," said Glass.

This year, he took the device to Flushing, New York.

"When I walked out onto Arthur Ashe stadium with a TNT Gauge in my hand to install it up there a couple of weeks ago, it was kind of the week knees moment for the inventor," said Glass. "It was the moment when you knew the industry and the game had begun to accept my product."

And things are just getting started for Glass and the gauge, Wimbledon came calling this week.

"I'm sending samples over to Wimbledon for their testing to be used in the 2013 Wimbledon Championships," said Glass. All they want to know is how tight to set their nets on their grass courts."
