The Sentry Longitudinal Energy Dissipater (SLED) is a narrow, non-redirective gating crash cushion. 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 SLED Euro-Terminal is the only free standing attenuation device that has been tested and accepted to EN1317-4 P4 requirements. Since the system is free standing, there are no pavement anchors, bolts or drilling to compromise the integrity of the roadway surface or bridge deck. The complete P4 SLED Euro-Terminal can be installed quickly with as little as one lorry and two workers and is designed to be placed on compacted dirt, gravel, decomposed granite, asphalt, or concrete.
The SLED Mini from TrafFix Devices is a MASH Tested and Passed as a Uni- and Bi-Directional applications and as a TL-1 End Treatment for the TrafFix Water-Wall™. With its stout design, the SLED Mini virtually eliminates vaulting of the impacting vehicle, even for larger vehicles such as Pickup Trucks and SUVs.
