The FAAC Skirted Barrier Boom Arm Kit (6.5 ft Opening) is designed to improve checkpoint security by blocking vehicles from slipping under raised gate arms. The skirt system is made of jointed metal sections that attach to the bottom of the barrier arm and fold away as the arm lifts. Lightweight construction ensures that the additional framework does not strain the motor. This kit includes both the skirt and mounting hardware for straightforward installation and reliable use.
