Kahuna 14ft 12 Pole Replacement Trampoline Safety NetThis net is made from tough weatherproof polyethylene which is reinforced around the top, middle and bottom. The netting holes are around 6 7mm in diameter reducing the chances of fingers getting caught. The entry door uses a high quality zip secured next to one of the poles (which makes it is bit easier to undo and do up) as well as clips. There are elastic straps with clips around the lower edge every 45 cm to secure the net around the perimeter.
