The Apollo discus cage can remain erected all season. That means throwers can train 24/7. Most cages have low wind ratings and spend most of their life in an unusable condition because the net is lowered. The Superstructure comprises of 3 poles galvanized & aluminum. Net comprises of 44mm square mesh, 2.5mm woven poly cord with 160kg breaking strain, black (green optional), UV stable, WA certified. Greater visibility of the athlete for viewing public, fewer implement strikes, with the superstructure skeleton positioned away from the netting. 5.5m high gate/net exceeds the new regulations - about to be introduced. 6m opening, 7m forward of circle centre. World Athletics and engineer certified. Price is for galvanised finish. Black finish extra, please enquire to confirm. WA Certified number E-12-0695.
