Donic Net tension gauge

DONIC NET TENSION GAUGE 
The ITTF-approved net tension gauge is used to determine the correct tension of table tennis nets in competitions. The 100 g metal net gauge is 1 cm shorter than the official net height of 152.5 mm at 142.5 mm. The measurement of the net is taken in the middle of the table and the tension is correct when the net gauge almost reaches the table surface when hanging freely.
