The QuadGuard LMC System meets NCHRP 350, Test Level 3 and is the ideal crash cushion for hazards in high-frequency impact areas. After a design impact, the system’s key structural components and energy-absorbing elastomeric cylinders are not expended. The QuadGuard LMC System is 100% reusable after most design impacts.
The QuadGuard LMC System consists of specifically formulated elastomeric cylinders surrounded by a framework of triple-corrugated steel diaphragms and Energy’s exclusive Quad-Beam™ side panels.

  • Non-gating, redirective crash cushion system
  • Performs effectively with both light cars and high center of gravity pickup trucks
  • Meets TL-3 (100 km/h / 62 mph)
  • Angles up to 20°
Head-On Impacts

During head-on impacts, the QuadGuard® LMC crash cushion system telescopes rearward, crushing the elastomeric cylinders to absorb the energy of impact.

Redirective Capability

When impacted from the side, QuadGuard® LMC redirects the errant vehicle back toward its original travel path without allowing gating.

Reusable Cylinders

Reusable elastomeric cylinders provide one of the lowest lifecycle costs of any attenuator.

Quad-Beam™ Panels

Quad-Beam panels provide 30% higher beam strength than thrie beam. Quad-Beam panels also protect the elastomeric cylinders and reduce rebound velocity.

Monorail Base

Monorail base eliminates the need for chains and cables providing excellent redirective capability.

Flex-Belt Nose

Flex-Belt Nose is reusable after most impacts.

Protects Wide Range of Hazards

Hazards from 910 mm (36 in.) to 2.3 m (90 in.) can be effectively shielded. Available in 910 mm (36 in.), 1.75 m (69 in.) and 2.3 m (90 in.) widths.

A Self-Restoring Crash Cushion System

QuadGuard® LMC will self restore after many, but not all, design impacts.
