Abstract: An improved animal barrier material and an improved fastening system to simplify its knotting process are disclosed. In the preferred embodiment, a plurality of multi-stranded metallic cables are joined together using parallel overhand knots. A pair of metallic cables may be taken together to form substantially adjacent portions which then form a loop. The pair of metallic cables passes around a portion of the loop and through the loop to form a overhand know. Such a knot minimizes stress and fatigue on the netting and makes the netting nearly invisible to the naked eye at a distance of more than a few feet.

Abstract: An improved animal barrier material and an improved fastening system to simplify its knotting process are disclosed. The animal barrier material comprises a see-through cable netting characterized by strong and secure knots. An improved fastening system may be employed to simplify knotting and produce superior cable connections. The improved fastening system requires only a single spool of cable to form grids for netting; its simplified knotting process does not require passing a spool of cable through any previously-tied portion of the net. The resulting cable netting provides a superior see-through netting for simultaneous containment and visual enjoyment of zoo animals.
