The net is 1 m wide and 9.50 to 10 metres long (with 25 to 50 cm on each side of the side bands), made of 10 cm square black mesh.
At its top a horizontal band, 7 cm wide, made of two-fold white canvas, is sewn along its full length. Each extreme end of the band has a hole, through which passes a cord, fastening the band to the posts for keeping its top taut.
Within the band, a flexible cable fastens the net to the posts and keeps its top taut.
