All-Electric Operation

The SENTRY Retractable Bollard features an all-electric drive with no hydraulic or hazardous fluids, making it an environmentally-preferable choice. Common breakdowns and worn components associated with traditional hydraulic systems are drastically reduced. The electro-mechanical drive delivers smooth, quiet and trouble-free operation and reduces maintenance significantly. Manual operation versions can be upgraded to electric operation at any future time if required.

Built for Integration

The SENTRY Retractable Bollard utilizes sophisticated control system drives for customized operation with available touchscreen technology interface and network communication. The control system easily integrates the bollard with other perimeter security systems such as speed detection, access controls, traffic loops, automatic doors, CCTV, gates, and other intrusion devices.

LEED Environmentally Preferable

SENTRY Retractable Bollards can contribute to LEED certification in up to six strategic categories.
