Kerbtech A

Kerbtech is an enhanced security traffic barrier, effectively used to protect targeted locations. The blocker is designed for simple and quick installation and is constructed to withstand harsh environmental conditions.

To enhance the blocker’s reliability, all the electrical controls and the hydraulic units are remotely sited above the ground in the vandal resistant, weather proof control cabinet.
