Abstract: A tonneau cargo net is fabricated of a single length of a low-friction rope formed into a knitted type of array having a substantially rectangular perimeter. The net consists of a multitude of non-jamming interlaced junctures having substantially the configuration of an overhand knot. The junctures are spaced apart by intervening portions of the rope and aligned in a series of parallel rows. The junctures in adjacent rows are staggered such that the adjacent junctures of three successive rows are disposed in a diamond-shaped locus.
