X-Tension® 110 P4 Terminal

The X-Tension® 110 P4 system is a tension based, energy-absorbing guardrail end terminal. It is able to cushion energy from head on impacts of up to 110 km/h, whilst redirecting the vehicle to a progressive and controlled stop.

Supply & Installation

X-Tension® 110 P4 terminal systems are available as either a single-sided or a double-sided terminal. Power and speed from the vehicle is absorbed through resistance, with the impact travelling along the tensioned rope, rather than being transferred down the steel beams, protecting against damage to the barrier structure.

The X-Tension® 110 P4 end terminal system is easy to install, improves safety and is easy to maintain and repair after impact, making it a cost-effective product.
