5. Operating Instructions

The Crab-Shaped Super Clamp offers versatile mounting options for various scenarios:

• Mounting on Round Pipes/Rods: The crab-shaped jaws are ideal for gripping round surfaces such as light stands, tripods, or stabilizer handheld rings. Adjust the jaw to fit the diameter of the pipe (14mm to 60mm) and tighten firmly.
• Mounting on Flat Surfaces: The clamp can also be attached to flat surfaces like table edges or shelves with a thickness up to 65mm. Ensure the anti-slip cushions make full contact with the surface for maximum stability.

  • 1/4"-20 Threaded Holes: Standard size for most cameras, small monitors, and many other accessories.
  • 3/8"-16 Threaded Hole: Larger size for heavier accessories or those requiring a more robust connection.
  • 1/4"-20 Locating Hole: Provides an anti-rotation feature when used with accessories that have locating pins, preventing unwanted movement.
• Combining with Magic Arms: For extended reach and flexible positioning, the clamp can be combined with a magic arm (e.g., SMALLRIG Magic Arm with Dual Ballhead ID: 2070B) by attaching the arm to one of the threaded holes.

6. Maintenance

To ensure the longevity and optimal performance of your SMALLRIG Crab-Shaped Super Clamp, follow these maintenance guidelines:

• Cleaning: Wipe the clamp with a soft, dry cloth after each use to remove dust, dirt, or moisture. Avoid using abrasive cleaners or solvents that could damage the finish or rubber cushions.
• Inspection: Regularly inspect the clamp for any signs of wear, damage, or loose components. Pay close attention to the screw threads, adjusting knob, and rubber cushions.
• Lubrication: If the adjusting screw feels stiff, apply a small amount of silicone-based lubricant to the threads. Do not over-lubricate.
• Storage: Store the clamp in a clean, dry environment away from extreme temperatures and direct sunlight.

7. Troubleshooting

If you encounter any issues with your Crab-Shaped Super Clamp, refer to the following common troubleshooting tips:

• Clamp is Slipping:
  • Ensure the adjusting knob is tightened sufficiently.
  • Verify that the clamping surface is clean and free of oils or debris that could reduce friction.
  • Check the rubber anti-slip cushions for wear or damage. Replace if necessary.
  • Confirm the clamped object's diameter or thickness is within the specified range (14mm-60mm for rods, up to 65mm for flat surfaces).
• Difficulty Tightening/Loosening Knob:
  • Inspect the screw threads for any obstructions or damage.
  • Apply a small amount of lubricant to the screw threads if they feel stiff.
