Model 775 Series Drop Arm Barrier


The Model 775 M50 Engineered Drop Arm Barrier is developed to provide the lightest operation arm with the greatest energy absorption capability.  Upon impact, the aluminum arm gives way to the energy absorption material secured inside.  The impact energy is transferred to the foundation though the surface mount stanchions.

B&B ARMR’s Drop Arm Barriers are available with several enhancement options to easily adapt to suit any application. For extremely cold weather, the receiver/latch post or arm may be equipped with a heater for uninterruptible operation or an electromagnetic lock can be installed for additional security during unattended times. An optional remotely mounted EPU/HPU drive provides flexibility for field conditions requiring a setup with centralized controls and components.

The Model 775 product line is developed with features and functions to allow for the easiest installation, maintenance and service.
