This is a 50 x 8' Nylon Netting. It is 5/16"mesh (hole). This netting is #139 nylon. 50 feet long and 8 feet deep. This netting is perfect for keeping birds out of your fruit trees or out of your chicken runs/coop! It is also great for baby poultry--even quail. It can also be used to keep leaves and debris out of your pond. Nylon will last a long time and not rot and it is UV treated. You can also cut this net into smaller pieces as needed. When cut the knots will not unravel. I bought this a few weeks back and then realized it would not work for our snow load so I'm selling it. It worked beautifully to keep the sparrows out of my runs/coop and I wish I could keep it... I would recommend it for use in warmer climates or somewhere that heavy snowfall is not an issue. The color is white but it can be dyed using RIT.
