X-350 Fully Re-directive Terminal End

The X-350 is the WORLDS FIRST fully re-directive guardrail terminal end that can be used in Median, Tangent or Flared (up to 1200mm) installations.

With the length of need starting at post 1, instead of post 3 (as in other terminals) the X-350 provides a greater length of protective barrier reducing the cost of installation. During end on impacts, the X-350 absorbs energy at the impact head rather than  transferring the resistance down the rail. Impact testing conducted at a 15° angle, showed the vehicle was re-directed and controlled instead of passing to the backside of the terminal.
