Security perimeter netting is the facility-grade barrier Gorilla Netting designs and installs around correctional and high-security sites to stop unauthorized access and toss-over paths. Turnkey: assessment, stamped engineering where required, poles/anchorage, hang.
Gorilla Netting sizes mesh density, panel height, and cantilever extensions to your fence line — high-tenacity polypropylene, nylon, or polyester with fire-retardant options where specifications require. Systems attach to existing perimeter fence or stand alone on wood or steel poles.
The netting system is usually made of high-strength materials, such as high-tenacity polypropylene, nylon, or polyester, and is designed to withstand various environmental conditions and potential threats. It can be installed at different heights depending on the facility's specific security requirements.
The primary purpose is to deter or prevent the delivery of contraband by perimeter fence toss-overs or other launch methods, such as potato guns, slingshots, or sports balls.

For overhead yard coverage and integrated contraband prevention, see our contraband netting page. Completed perimeter work includes CoreCivic McRae, Northeast Ohio Correctional Center (NEOCC), CoreCivic Wheeler, and Puerto Rico Department of Corrections — see related projects above.
The methods used to bring contraband into secure facilities are becoming increasingly sophisticated, ranging from high-tech drone drop schemes to low-tech methods like tossing items over perimeter security fences. Narcotics, phones, tobacco, and weapons are often hidden in bags or sports balls and thrown over fences, posing a significant threat to the security and safety of your facility.
