Difference betwwen 2 piece (Mastercone) and 1 pice (E-Cone) Road Cones
One piece road cones such as the E-Cone (also known as the Roadhog cone) are not suitable for road highway use and are typically used for event crowd control, vehicle access on private roads and estates and for mounting
road cone signs on.
Two piece road cones such as the Mastercone (also known as the Dominator road cone) are UK road highway legal and are more robust than the E-Cone. If they are hit by a vehicle, the bottom breaks away from the cone which usually allows the road cone to be re-erected and used again.
