The extruded aluminum blades are mounted with friction minimizing nylon bushings to provide easy transition between opening and closing.The DuroZone Spring Return Multi-Blade Dampers also feature damper blades designed to remain within the damper frame for easy insertion and an external side-mounted linkage for smooth and quiet operation. Multi-Blade dampers are available in 74 stock sizes with a 24-volt spring return “Mid-Torque” motor.
