The HV2 Barrier is the ultimate freestanding, temporary longitudinal barrier system, bringing improved productivity and safety to worksites. The barrier's patented hybrid technology and unique connectors offer high containment and low deflection, while remaining economical to transport and deploy with no time-consuming anchoring required.

The HV2 Barrier is MASH TL-4 tested, passed and eligible; offers high containment ability with safe redirection. It is designed to distribute and contain the force of an impacting vehicle without being anchored to a road surface making it an excellent choice for concrete bridge decks with no potential damage to the rebar. Only the damaged barrier needs to be replaced, making them extremely economical. Compatible with the Sentinel Impact Tracker to create an Intelligent Steel Barrier!

The HV2 compatible with the SLED end treatment and a variety of end treatments from different manufacturers. It is economical to transport, install, and retrieve and can be used on any flat surface. Strong "S" connectors keep barrier sections securely linked while being extremely simple to setup without the need for pins or bolts.

HV2 Approval Status

HV2 Safety Barrier is a free standing temporary longitudinal barrier system successfully crash tested to MASH TL-3 & MASH TL-4. The patented hybrid technology, and unique connectors, allow it to offer high containment and low deflection, while remaining economical to transport and deploy. HV2 Safety Barrier also provides safe, consistent and reliable redirection, fast deployment and retrieval. No anchoring is required with no loose parts making it maintenance free with the durability of galvanized steel.

HV2 Safety Barrier is tested to provide positive protection of work sites by safely redirecting errant vehicles up to 22,000 lbs (10,000 kg) at 15° and 56 mph (90 km/h), or 5,000 lbs (2,270 kg) at 25° and 62 mph (100 km/h). This allows HV2 Safety Barrier to be suitable for use on any roadside work zone from highways to low-speed local streets. It can be used on any firm surface including concrete, asphalt, spray seal, unsealed compound pavements, and uniform natural surfaces.

The HV2 Safety Barrier is constructed from a series of individual barrier segments. Each segment is constructed from galvanized steel with required concrete ballasting. Segments are fastened by integrated, interlocking bidirectional connectors, which simply slides together when barriers are lowered into position.

HV2 Safety Barrier installations require a minimum deployment length of 323.5 ft / 98.6 m (17 interlocking, ballasted HV2 Barrier units) plus the required end treatments, to safely contain and redirect at MASH TL-3. For MASH TL-4 the minimum Deployment is 912 ft / 278 m (48 interlocking, ballasted HV2 Barriers) plus the required end treatments.
