The basic design of cable barriers consists of heavy-duty cables
strung along a row of posts. The cables are tensioned to provide
enough strength and give to safely catch misguided vehicles like a
net, thus avoiding head-on collisions. Approximately 30 inches
tall, the cable barriers are positioned low to efficiently catch
most misguided vehicles around the vehicle chassis, grill and/or
bumper and safely redirect them away from opposing traffic.
