Home > Companies > Heras > 94x Series HVM Barrier

A range of heavy-duty, vandal resistant dual beam barriers which have been crash tested to PAS 68, achieving a high rating for stringent crash certifications. The 94x series is scalable, offering the potential to upgrade protection levels if site security requirements are increased.

Incorporating a shallow foundation mounting system, the installation of this barrier is simple and low-cost, suitable for perimeter or internal/ on-site applications. Capable of controlling high volumes of traffic, the barrier is designed to protect high-risk sites where vehicle impact attack is a threat.

The innovative, lightweight dual beam cassette design allows for faster operation and greater lifetime durability than traditional heavy systems. This feature ensures that beam replacement is quick and easy in the event of attack/ impact, minimizing any security downtime onsite. Safety is central to the design of the range, with sleek protective shrouds and laser scanners.

Features and benefits:

  • Lightweight composite cassette beam allows boom replacement within 60 minutes.
  • Suitable for high traffic throughput.
  • Proven protection for high-risk sites.
  • Shallow foundation for easy installation.
  • Declaration of Performance (DoP) certified to EN 13241 and PAS 68 tested to ensure both security and safety of operation.


While the barrier is primarily intended for use to protect site perimeter security, it can also be used within site boundaries to protect specific or sensitive areas and can be used with other vehicle security equipment to create very high-security air-lock solutions. Available in a variety of sizes, this series has been crash tested with a clear opening up to 6 metres.
