February 2020 – Update of New Zealand Transport Agency (NZTA) Specification M23 Appendix A, has deemed ET2000 Leading End Terminals to be a legacy system – repair use only, not for new highway installations. Site Specific acceptance (from NZTA) required for use on structures.
For a MASH Compliant system, please refer to SoftStop End Terminal.
The ET2000™ PLUS (Guardrail Extruder Terminal) end terminal is engineered to absorb the kinetic energy of an impacting vehicle on a road safety barrier. This is accomplished by deforming (flattening) the guardrail. The terminal is designed to reduce the problems associated with impacting vehicles, such as spearing, vaulting and rollover. A primary advantage of the ET2000™ PLUS is its non-flared characteristic. The ET2000™ PLUS provides an end treatment solution for applications where there is insufficient space for a flared end terminal or when it is cost prohibitive to place embankment for a flared system.
The ET2000 PLUS™ end terminal is available in two sizes. The compact 7.62m NCHRP 350 Test Level 2 terminal is an economical solution for application where the posted speed is = 70km/h. The standard 15.24m NCHRP 350 Test Level 3 terminal is acceptable for all posted speeds > 70km/h.
