The advantages of a barrier arm unit are:

• Easy ADA and cargo throughput.
• Physical barrier instead of a "beep"
• Optomechanical "anti-tailgating"
• Good two-way traffic control

Linear is the name we gave to the second of This Century's Turnstiles!

Aeroturn's Linear principal features are:

• Zero-Maintenance through a minimum of 10,000,000 cycles.

• Easily overridden if inadvertently contacted when arm is in motion.

• 22-36" Passageways with a single arm unit.

• 36-72" Passageway with a double (opposed) arm unit.

• Front Panel Emergency Release that is activated with the supplied Aerokey. Safely lowers arm when activated and auto-secures the passageway when deactivated.
