Protek 358 Clamp

Flat Panel Clamp Security Fence System

The Protek 358 Clamp system is designed to be almost impossible to climb, due to the narrow apertures of the mesh preventing any potential intruder from gaining a foothold.

Protek 358 still maintains a good level of visibility through the fence, while the strong wires used in the mesh panels are incredibly hard to penetrate or cut using standard cutting tools. Each Protek 358 fencing panel is overlapped with a full-height clamp bar with multiple anti-tamper fixings, forming a fence line that provides a very high level of security.
