A bollard is a sturdy, vertical post. The term originally referred to a post on a ship or quay used principally for mooring boats.
"PRICE INCLUDES CARRIAGE AND V.A.T." Metal Removable Bollards can be used to prevent unauthorised entry of vehicles and restrict access to private driveways, forecourts, car parks, town centres, supermarkets and garages, but still give pedestrians access. These bollards are much more ascetically pleasing than cones and are heavy duty, locating into a socket embedded into concrete and are low maintenance.
