Articulating gate arms are necessary when the gate is installed in parking garages with ceilings that are limited to about 7ft. In such cases, the arm is cut in the middle with a mechanism so the arm takes a inverted L shape when opened and fits within the restrictions of the ceiling, but still allows clearance of about 6’-6” or so for most vehicles to pass under them.
Our articulating arm is designed with reflective tape and can be added to any barrier gate in our product line.
