Security Bollards

Retractable Security Bollards

Retractable security bollards from A.C. Miller allow for controlled vehicle access to areas where security or restricted access is required.


  • Pedestrian Drop-off or Pick-up Zones
  • Parking Structures
  • Roads, Alleys, Driveways
  • Pedestrian Walkways
  • Pedestrian Bike Paths
  • Outdoor Pedestrian Malls/Plazas
  • Building/Facility Protection


Retractable bollards provide an affective, durable solution for applications where regulating vehicle access requires rapid lowering and raising of the bollard barrier.

The retractable bollards rapidly retract down into the lowered position to allow for traffic entry/exit while sitting flush with the ground, so they are neither a tripping hazard nor an obstruction for pedestrian traffic. When  raised into the secure extended position, they provide a physical impact resistant barrier that prevents entry or exit or vehicle traffic.
