The Avon RB880 CR Defender High Security Road Blocker is a shallow or surface mounted road blocker which provides a high level of security against unauthorized vehicle access where excavation depth is limited.
Designed to withstand substantial direct impact forces, the Blocker can protect sites from extreme aggressive attack.
Designed and Manufactured by engineers with a wealth of experience in the fields of High Security and Access Control, the RB880 CR is a highly dependable security product that will easily interface with a wide range of control equipment.
Units are assembled in our UK fabrication facility using heavy gauge materials to give maximum strength and durability. This makes the RB880 CR the ideal product to protect high security establishments.
The RB880 CR has been independently physically tested in a number of full scale crash tests by the Transport Research Laboratory (TRL). This led to the RB880 CR becoming the first British built Shallow mount Road blocker approved by the UK Government.
