The RB50 is a versatile piece of equipment designed for rapid deployment to stop a vehicle on contact, thereby protecting against both vehicle incursions and vehicle as a weapon attacks.
RB50 can be installed as effective hostile vehicle mitigation (HVM) protection as part of a counter terrorism strategy for events and locations, or to prevent errant or malicious incursions into work areas, road closures or secure sites.
IWA 14-1: 2013 and PAS 68: 2013 rated, RB50 is almost always deployed in ‘as tested’ four-metre arrays, which can be put in place in minutes, moved quickly to enable authorised vehicle access, and easily reconfigured for complete flexibility.
The robust, galvanised steel units have wheels that can be used to position and reposition each array quickly and easily, then removed to ensure the RB50 unit remains securely in position.
When not in use, the RB50 HVM system can be dismantled for compact storage in specially designed stillages that enable two arrays – the equivalent to 8m of HVM protection – to be stored in a single 1.2m2 stillage.

Testimonials
“At SAFECROWDS GROUP we use a range of rated HVM systems, specifying the most appropriate equipment to mitigate the identified risk and align with our clients’ operational and crowd management needs.
RB50 is often the HVM system of choice for our deployments because it provides effective protection against vehicle as a weapon attacks and vehicle incursions. It also gives us the flexibility of rapid deployment and de-rigging, along with compact storage, ease of transportation and scalability. We know when we deploy RB50 that our trained technicians can install each array in around five minutes and move it aside in seconds to enable emergency vehicle access, while keeping pedestrians safe in the protected area. It’s an excellent, versatile option for hostile vehicle mitigation to protect road closures.”
“At Crowdguard, we select solutions that are practical, proportionate, and deliver confidence in both safety and operation. The RB50 from Block Axess has proven to be an outstanding addition to our portfolio because it combines robust security performance with real world usability.The RB50 is designed with deployment in mind. Transportation and storage are made simple with dedicated stillages, and installation is quick and straightforward thanks to the click-and-lock system, eliminating the need for pins that can be easily lost and compromise integrity. Once in place, the 360 degree swivel wheels make manoeuvring effortless, while the option to remove the wheels entirely transforms the unit into a static barrier that provides enhanced, reliable security.For our clients, this means protection they can trust, delivered efficiently and with complete assurance. For us as an operator, it’s a solution that strikes the right balance between security, simplicity, and strength.”
