Any roll: double twisted mesh weight calculator.
The designer sets the anchors, ropes and spacings for the slope; the netting is the part we supply. In outline: rolls are hung from a top support rope anchored along the crest, unrolled down the face, laced to each other along every vertical joint with lacing wire or rings, and left free at the toe so that falling rock collects in a catch ditch. On higher-energy slopes the mesh is reinforced with steel ropes and rock bolts. Rockfall netting →
