RamShield® Median features a strong section C-post supporting back-to-back w-beam, providing safe vehicle containment and redirection when impacted from either side of the system.

The separation of the rail from the post is achieved by a release tab incorporated into the post. The tab controls the release of the rail within the impact zone providing stable vehicle containment and redirection with minimal vehicle roll.

RamShield® Median has been fully crash tested and evaluated according to the specifications for Test Level 3 (TL3) of the AASHTO Manual for Assessing Safety Hardware (MASH). The MASH specification is an update to and supersedes NCHRP Report 350 for the purposes of evaluating new safety hardware devices.

The MASH specification is an update to and supersedes NCHRP Report 350 for the purposes of evaluating new safety hardware devices.

MASH presents uniform guidelines for crash testing permanent and temporary highway safety features and recommends evaluation criteria to assess test results.

MASH considers real-life crash data, changes to the vehicle fleet and in-service performance in developing evaluation criteria.
