Wire & Cord
Seven-stranded, stainless steel wire, coated with U.V.-stabilized clear nylon. Diameter is .7mm with a breaking strength of 100 lbs.
The stainless wire offers lower visibility for sensitive areas, whereas the polyester cord is more of a visual irritant to the birds. Both options create the barrier to deter large bird species. Leaving a little slack in the line adds another imbalance for those that try to perch. Use the cord if a non-metallic installation (for communication towers and radar installations) is required. 500 ft.
