Intermediate barriers (V28) are symmetrical in cross-section and can be used for either verge of central reserve applications, by turning them upside as shown below. Barriers should be aligned according to the direction of the traffic flow, using the directional arrow cast in the face for orientation.
Termination units are handed, being specific to Verge Applications (V29) or Central Reserve Applications (V30).
Units are connected together at the scarf joint, using M24 diameter high-tensile bolts. Units can also be fixed to the carriageway if required, by use of anchor plates bolted to the underside of the barriers.
