Trief Chevrons are interlocking kerbs that have the same design specification and qualities as the standard units and are very effective for directional indication at road bends and roundabouts.

The unique chevron design is extremely effective for marking traffic islands and roundabouts. The units feature the same design, specification and production qualities as the Trief and Trief Cadet units.

Trief Chevron units are available in a choice of surface finishes: marker for a non-reflective finish or Ballotini finish containing Ballotini glass beads for a reflective surface finish.

Both are available in black and white. Other colours are available on request.

The Trief Containment Kerb system has been widely used to form traffic calming features, pedestrian refuges and to protect bridges and can also be used to enhance security features by reducing traffic speeds and as a visual and physical deterrent to deliberate incursion.

Trief Chevron Kerbs are manufactured in accordance with BS EN 1340: 2003. CE marked.
