Non-Locking Bollards for Equipment Protection and Traffic Guidance

Non-locking removable bollards are ideal for a variety of applications where a locking bollard system isn’t required.  One application is inside already secure facilities to protect equipment of all kinds from accidental vehicle incursions.  This can save thousands of dollars in damages and repairs.  They can also be easily removed by simply twisting the bollard post to gain access in the event equipment, such as a generators, need to be accessed for maintenance or repair.  Another ideal application is for protection and traffic guidance at secure facility entrances such as military installations which are typically secured by authorized personnel and there is no threat of the bollards being removed by an unauthorized user.   An additional feature of the round post twist in series is that it creates the illusion that the bollard is actually locked into place, deterring an unauthorized user from removing the bollard.

The TrafficGuard® twist in series is shipped with either a ground sleeve / filler piece option or a lidded sleeve.  These ground sleeve options are used with a variety of other TrafficGuard® removable locking bollards offering end users the flexibility to use locking and non-locking bollards interchangeably depending on their evolving security needs.
