Swing Arm Height Restrictor

Swing Arm Height Restrictor Barriers – Built for Access Control and Clearance Protection

Available in multiple heights and widths, the Swing Arm Height Restrictor from Barrier Stop Defense is engineered to prevent over-height vehicles from entering parking garages, car parks, or restricted areas. Choose from several models:

• Single Swing Arm Height Restrictor
• Double Swing Arm Height Restrictor
• Adjustable Arm Height Restrictor

Each swing arm barrier can be unlocked and opened to allow access for emergency personnel or approved vehicles. Optional locking mechanisms, Knox boxes, and safety features make it easy for authorized users to gain entry when needed.

Also known as height restriction barriers, truck height notices, or overhead clearance barriers, these systems provide a simple, effective way to protect structures with low overhead clearance from vehicle damage. The moveable swing arm crossbeam is mounted to a heavy-duty upright post, creating a secure and durable restriction point.

All Barrier Stop Defense products are engineer-stamped, USA-built, and constructed from 100% American steel and aluminum. With custom height and width options, our barriers suit everything from single-lane entrances to large commercial driveways.

For extra-wide driveways, our cable height restrictors offer a versatile alternative, allowing for custom signage or clearance warnings.

Whether protecting parking garages, loading docks, low bridges, or sensitive entry points, Barrier Stop Defense can design and build a custom height restrictor that matches your specifications, including custom colors, spans, and branding.
