HOW TO CHOOSE A VOLLEYBALL NET

Modern volleyball nets are made according to the “no-knot” technology, from synthetic fiber (usually polypropylene) in a special way woven into durable threads. By the way, the thicker the thread – the more quality the mesh is considered. It also depends on the thickness of the threads how long the network will serve you. Typically, the thickness of the filaments forming a volleyball net is from 1.2 to 4.2 mm. According to the FIVB rules, volleyball nets must have a steel or kevelar cable of lower tension of 6-8 cords of lateral fastening.

The nets used for amateur volleyball or training, of course, do not necessarily meet the requirements of the FIVB – in such cases there are 4-cord side mounts, and the lower tension cable has less strength.The fiber itself and the quality of the threads are worse. But such nets are much cheaper. Which volleyball network you decide to buy.

The most popular manufacturers of nets: KV.Rezac (truly the best combination of price and quality), Huck and, of course, Mikasa (expensive, cool, high quality). Models Mikasa VNC, Mikasa Q7VNETTA, Mikasa Q7VNETTB – are the official grids of the International Volleyball Federation.
According to the rules of professional competitions, volleyball nets must be equipped with antennas that are installed in special pockets attached with Velcro to the net.
