MASH SLED™ Crash Cushion

The Sentry Longitudinal Energy Dissipater (SLED) is a narrow, non-redirective gating crash cushion that is designed to shield permanent and temporary barriers including concrete, steel, and plastic, and which has been crash tested to MASH TL-3.

The SLED™ is designed to shield the end of all permanent and temporary portable barrier shapes including concrete, steel and plastic. SLED's unique design incorporates four internal steel cables which help envelop the impacting vehicle, reducing the possibility of secondary accidents. The SLED™ End Treatment does not require foundation anchor bolts to be attached to the road or bridge deck. The complete crash cushion can be installed quickly, with as little as one pick up truck and two workers on compacted dirt, gravel, decomposed granite, asphalt or concrete.

Each SLED™ module is manufactured from a high visibility yellow polyethylene that is UV stabilised to minimise degradation. It is designed to deform and rupture on impact, absorbing the energy of the errant vehicle. SLED™ has the most versatile transition for shielding all permanent and temporary portable barriers. The combination of hinging and contouring, allows the transition panels of the SLED™ End Treatment to be attached to narrow, wide or other profile shapes with either converging, or diverging angles, up to 10 degrees.

  • FHWA accepted for shielding the blunt end of concrete, steel and water filled barriers
  • Quick and easy set-up with no foundation anchoring required
  • Universal transition quickly and easily attaches to a variety of barrier shapes and sizes
  • SLED's stout design virtually eliminates vaulting
  • A narrow footprint is Ideal for work-zones or roads with minimal shoulder spacing
  • Shortest length TL-3 water filled crash cushion meaning fewer incidental impacts
  • Containment impact SLED minimizes debris field
  • Visual ‘Drive By’ fill indicators allow for quick verification if barriers have been properly filled
  • FHWA accepted for use in uni- and bi- directional applications
  • Internal steel cables help envelop vehicle after an impact, creating a truly ‘limited gating’ system
