Drop Arm Gate

The DROP ARM GATE (DAG) combines the utility of a traditional traffic control gate with the security of a crash-rated barrier to deter, deny and delay threats as they occur. The DAG offers crash-rated protection up to 20,000 lbs at 50 mph and can secure multiple lanes of traffic or wide checkpoints, up to 24 feet. This product provides security, access, and safety for government, utility, energy, manufacturing, industrial, or commercial properties.

The unique, fully-vertical position (90° up) allows for unobstructed use of the roadway, safe positioning of the arm, and minimal setback from the roadway opening. The DAG includes a positive locking device for securing the arm in the down position. The DAG’s passive safety latching mechanism engages on vehicle impact. The DAG is available in manual and operated models. The operated DAG is entirely electro-mechanical, making it ideal for sites where hydraulic fluids are prohibited. Counterweights can be adjusted in manual operation to require minimal force for raising and lowering.

Boasting a duty cycle of 120 cycles per hour, the electro-mechanical DAG allows for fast processing of vehicles at controlled access points. It features a warning horn, flashing light, edge sensor, and photoelectric sensor in accordance with UL 325 standards. Operated models include control panel, controls, and electro-mechanical operator; and is preconfigured for easy integration of additional access control and safety devices as well as integration of barrier command and control from multiple control locations.

The DAG’s modular option with a concrete barrier mount requires no excavation, allowing you to place them at virtually any location.

  • No excavation
  • Easily placed and relocated
  • Forklift and lift hook compatible
  • No site or foundation preparation required
  • The DAG with a standard foundation can be installed across existing roadways with only minimal excavation and primary excavation is outside the roadway opening, avoiding underground utilities and other obstructions.
  • Minimal excavation outside roadway opening
  • Zero set-back from roadway
  • Small footprint

what they're saying

I want to take this opportunity to let you know how much we appreciate the efforts of you and your team in assisting with our security posture throughout the week of the Democratic National Convention in Charlotte, North Carolina. From the procurement of the fence product itself, to the set up and take down, your staff was professional every step of the way. Our folks and others had nothing but positive things to say about the appearance and functionality of the product. Please ensure your team and leadership receive this as this has been a wonderful partnership that we hope to continue with. Thank you to you and your team again.

As the former Construction Manager for the Front Gate (MILCON) project at Parris Island, SC, it is my pleasure to provide my input regarding the construction of this project. In my view, you and your team, brought unmatched qualities that ensured the successful completion of the Front Gate project. Honesty, diligence, knowledge, competence, reliability, experience, commitment, and professionalism are only some of them. However, the most impressive quality I observed was simply 'wanting to provide a great product'. It was that 'attitude' that helped overcome a wide array challenges in a timely manner. The successful completion of the Front Gate project is a great testament that, with the right people, a project can be done right, in time, and within budget.

Global GRAB is a powerful and strong defense company. The team is extremely helpful and operates a great facility.

The GRAB Barriers were selected because they were considered by the Provost Marshal’s Office to be the only Non-Lethal barrier that met or exceeded every State, Federal, and Army Standard for stopping a specific “Threat Vehicle” and with less risk to drivers and occupants.
