A Tube Net is a tube made of rope; like the name implies. We build our Tube Nets with a 3' diameter, which is approximately a 9' circumference, and either a 9" or 12" square grid pattern. The mesh ropes are 3/4" and the two ends are surrounded with a 1" frame rope. The cylindrical ropes are joint spliced down one side looking as if the net has a seam. We offer our Tube Nets by the square foot. To calculate how many square foot you want multiply the length of your tube net the by 9' circumference = square feet. Enter the total square footage in the quantity box in your shopping cart. If you require a tube net with a different size diameter please submit a contact form and we will assist you.
