Security Perimeter Netting Systems

Defend Against Contraband

What is a Gorilla Netting Security Perimeter Netting System?

Gorilla Netting Security Perimeter Netting Systems are specialized netting structures designed to protect a secured area from unauthorized access or intrusion. It is typically installed around the perimeter of a facility, such as a prison, jail, or other high-security location, to prevent the entry of contraband or other unwanted items.

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.

Contraband Netting

Contraband netting is the overhead and vertical barrier layer that stops phones, narcotics, tobacco, and weapons from crossing your perimeter by toss-over, slingshot, or modified sports equipment. Gorilla Netting sizes mesh density, panel height, and cantilever extensions to intercept trajectories above existing razor wire or chain-link fence lines without creating maintenance dead zones.

Our contraband netting installs use high-tenacity polypropylene, nylon, or polyester with fire-retardant options where specifications require. Panels attach to existing fence infrastructure or standalone poles painted to blend with facility aesthetics—installed under security protocols for active correctional environments.

Prison Netting

Prison netting systems integrate perimeter fence extensions, cantilever arms, and full-height barrier panels engineered for jails, state prisons, and federal correctional campuses. Gorilla Netting's law-enforcement background informs layouts that address real-world launch methods—from potato guns to drone drops—while meeting wind and structural codes for your region.

Whether you are retrofitting an existing yard or specifying netting for new construction, our prison netting scope includes site assessment, custom height design, professional installation, and a full warranty on completed work. Facility security staff receive documentation for procurement and ongoing inspection cycles.

The Growing Threat of Contraband

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.
