<p>A bracket (28) for supporting a rail (20) of a roadside crash barrier or parapet (10) from a support post (12) is disclosed. The bracket is formed from a single sheet of metal bent into a shape, which, when mounted to a post and supporting a rail, has a uniform horizontal cross-section including parallel front and rear panels for mounting to the rail and post respectively, and interconnecting sides. The shape of the cross-section provides a first deformation mode of the bracket in the event of an impact to the rail exceeding a first impact level, and a second mode of deformation of the bracket in the event of an impact exceeding a second, higher impact level.</p> |
