Telescopic Security Posts & Bollards' are by far the strongest type of posts & bollards used for protecting driveways and entrances, the strength comes from the simple fact that more of the structure is underground than above..
When the posts are not in use, the inner post simply slides easliy into the ground leaving a totally flush finish, which prevents any chance of damage to the underneath of a low car etc, and with the fact that it is far more aesthetically pleasing to the eye when not in use.
