The OBB Post Connector Plate, also known as an Open Box Beam Clamp Plate, is used to securely fix Open Box Beam (OBB) crash barrier rails to both bolt-down and dig-in support posts. It is compatible with RSJ and Z posts, providing a reliable mounting point for OBB barrier systems.

During installation, the clamp plate is fixed to the post using Armco barrier post bolts (sold separately). Once in position, the open box beam rail can be slotted into place, allowing for a fast, adaptable installation process.

Open Box Beam barrier systems are engineered to offer greater strength than traditional corrugated Armco barriers, making them well suited to areas exposed to heavy vehicle impacts. As a result, these connector plates are commonly used in locations such as loading bays, private roads, car parks, factories, and industrial sites.

Manufactured from high-quality galvanised steel, the clamp plates are suitable for both indoor and outdoor use. The galvanised finish provides long-lasting protection against corrosion, weathering, and surface deterioration.

We supply a full range of Armco barriers, posts, and accessories, enabling the creation of durable safety systems designed to protect buildings, infrastructure, and pedestrians from vehicle damage.
