TrafFix SLED

The SLED (Sentry Longitudinal Energy Dissipater) end treatment is a gating, non-redirective crash cushion used to shield permanent and temporary barriers of all sizes. This system is one of the shortest MASH Test Level 3 water filled crash cushions on the market and can be used in uni- and bi-directional traffic applications. A Containment Impact Sled (CIS) is attached to the front module and is held in place with four internal steel cables. These features help conceal errant vehicles during impacts and help reduce the potential for secondary impacts.
