The TNT Gauge System

Tennis Net Tension

The only proven, user-friendly, certified accurate, patented, and inexpensive way to measure net tension, so that all courts play equally.  Ready for delivery now.  Don't be fooled by claims that center-strap or singles sticks net tension devices can do the same.  Only the TNT Gauge and its direct connection to the net cord will measure net tension!

TNT Gauge has been installed on competition courts at the US Open

for 7 consecutive years, including 2018!

The USTA NET TENSION RECOMMENDATION is in effect! Since 2015, USTA's Friend at Court Comment 1.1 clarifies Rule 1 (The Court) of The Rules of Tennis by recommending 400-450 pounds tension "with the tension of all nets within 25 pounds of each other.  Use a net tension device when available."

ITF has a net tension recommendation, at this ITF Technical page, based on work with the TNT Gauge.

The TNT Gauge is the only accurate and patented net tension device in production.
