The Nailor CDQUAD/HLQ Hand Locking Quadrant is primarily designed for use with the Nailor Multi-Blade 1800 Series Manual Balancing Dampers, 1000, 1100, and 2000 Series Control Dampers.
It mounts directly over a 1/2″ (13) dia. lock-on drive shaft or a rigid 1/2″ (13) dia. drive shaft and is secured with a carriage bolt.
The CDQUAD is provided with pre-drilled mounting holes for convenient installation and the design ensures that the mounting screws do not interfere with any damper side linkage that may be hidden inside the damper frame channel.
