NN3 Small Knob for Camera or Vertical Rail Mounting

Smaller diameter Camera Mounting Knob and/or Vertical Rail Knob for NN3 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.
No charge for swapping the standard vertical rail mounting knob with these smaller diameter knobs during purchase of NN (mention in notes section during checkout).
