The SLED is designed as a barrier system to shield the end of all permanent and temporary portable barrier shapes, including rigid concrete barriers, steel barriers, and plastic. SLED's unique design incorporates four internal steel cables, which help envelop the impacting vehicle, reducing the possibility of secondary accidents and other roadway hazards.

The SLED End Treatment does not require foundation anchor bolts to be attached to the road or bridge deck.

The complete cushion crash attenuator 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 stabilized to minimize degradation.

It is designed to deform and rupture on impact and absorb the impact 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.
