The Sentry Longitudinal Energy Dissipator (SLED) is a narrow, water-filled, non-redirective, gating crash cushion system. The SLED has been crash tested to MASH Test Level 3 standards. The SLED is designed to shield the end of all permanent and temporary portable barriers. The SLED’s unique design incorporates four internal steel cables, which help envelop the impacting vehicle. Thus, reducing the possibility of secondary accidents.
