Barrier1 Systems’ drop arm barrier gates provide controlled vehicle access across spans up to 24 feet while delivering certified ASTM-F2656-M50 crash protection. Unlike fixed bollards that create permanent blockades, drop-arm gates offer operational flexibility, enabling facilities to maintain both security and controlled vehicle access.
With surface-mounted, in-ground, and kit-based installation options, these American-made systems deliver proven performance for high-security facilities worldwide.
| System | Model # | Crash Rating | Spans | Operation | Foundation Type | DoD Listed | Made in USA |
|---|---|---|---|---|---|---|---|
| Avenger M50 Electric Drop Arm | DACB-ELE-1200 | M50-P3 | 14'-24' | Electric | Surface-set on 6" concrete pads | Yes | Yes |
| Avenger M50 Manual Drop Arm | DACB-MAN-1200 | M50-P3 | 14'-24' | Manual | Surface-set on 6" concrete pads | Yes | Yes |
| Phantom M50 Fixed Electric | FCB-1200 | M50-P2 | 12'-16' | Electric (6 sec) | 42" in-ground | Yes | Yes |
| Hellfire M50 Kit Drop/Swing Arm | KBVB-MAN-1200 | M50-P3 | 14'-18' | Manual | Kit-based mount | Yes | Yes |
The vertical drop arm configuration presents unique engineering challenges compared to horizontal swing barriers. The elevated arm must absorb and redirect impact forces while maintaining structural integrity across the full barrier width during downward impact.
Every Barrier1 Systems drop arm barrier gate has passed full-scale, third-party crash testing with 15,000-lb vehicles at 50 mph impact speed to verify M50 stopping capability. These barriers are available at different penetration ratings (P2, P3) to address varying security requirements across multiple facility types.
Penetration Performance:
Unlike swing arms that require lateral clearance space, drop arms operate vertically, making them ideal for constrained entrances where horizontal space is limited. Facilities can control vehicle access while maintaining apid barrier deployment in the event of a security threat.
Proprietary vertical barrier design provides full M50 crash protection across spans up to 24 feet, delivering consistent performance under impact conditions.
Supports surface-set, in-ground, and kit-based installation options—allowing deployments that adapt to utility conflicts, power constraints, excavation limits, and unique site requirements.

These are the most common questions our barrier experts hear about Barrier1 Systems’ drop arm barrier gates:
Drop arms operate vertically, requiring minimal horizontal clearance space. They are ideal for narrow entrances where swing arms would interfere with adjacent structures or traffic lanes.
Electric systems automatically secure in the closed position during power loss and can be operated manually if needed. Manual models function independently of electrical power, maintaining full crash-rated performance during outages.
Maintenance requirements will vary based on site conditions. In most cases, drop arm barriers require only basic servicing such as monthly visual inspection of arm assembly and pivot mechanisms, quarterly lubrication of moving components, and annual testing of safety systems. Modular construction enables component replacement without system downtime.
The P-rating denotes the distance the test vehicle traveled past the barrier during crash-testing. P1-rated systems stop vehicles within 3.3 feet for maximum security. P2-rated systems (like the Phantom drop arm) allow 3.31-foot to 23.0 feet of penetration for high-security areas. P3 systems (Avenger, Hellfire) allow 23.1 to 98.4 feet of penetration for broader facility protection.
Yes, Hellfire Kit-Based systems achieve full, crash-rated M50-P3 performance when properly installed on concrete barriers meeting manufacturer specifications.Vertical Security Solutions for Critical Access Control
