Net Fence (sometimes referred to as Pop Fence) is a very durable fence that is constructed from 3.5mm polyethylene with a knotted 4" square pattern and is reinforced and overstiched along the entire perimeter for extra durability. Ideal for race courses, caution barriers, and high wind areas. Net Fence exhibits excellent UV resistance and is available in high visibility orange or blue. Each roll comes 44" high by 100' long.
