NN3 MKII Small Knob for Camera or Vertical Rail Mounting
Smaller diameter Camera Mounting Knob and/or Vertical Rail Knob for NN3 MKII series pano heads.
The smaller knob design allows greater inward adjustment needed with many point and shoot cameras and also some pano heads using the RD3L rotator. Good for NPP from 28-40mm from upper rotator center.
