OBEX MT P4 Terminal is the first terminal system in the world to be successfully tested to prEN1317 Part 7. All test results have been fully validated by AISICO (Notified Body) and thereafter peer reviewed by the world renowned testing facility TRL.

The design of the product has been developed to provide the safest performance to terminate and anchor guardrail in high speed situations. It behaves much like a crash cushion in how it absorbs the energy of vehicle impact with the compression of its unique energy absorbing steel cellular sections. The design reflects a new generation of P4 Terminal that is a departure from conventional systems based on corrugated beam profiles. Such corrugated beam systems have been known to malfunction if installed incorrectly and can present a hazard such as spearing of vehicles.

The OBEX MT P4 complies with EN1317 part 4 and prEN1317 part 7 (T110).

Please download the system brochure for more detailed information on the range of applications.

The OBEX Modular P4 Terminal design concept is unique, innovative and covered with a Patent Pending application (UK No. 1421308.6).

OBEX MT deve essere installato da installatori OBEX formati e certificati solo in conformità con il Manuale di installazione OBEX.
