Setup and Assembly
1. Attaching the Magic Arm
The magic arm features a 1/4"-20 screw with retractable anti-twist pins on one end. To attach your device (e.g., action camera, monitor, light):
- Align the 1/4"-20 screw with the mounting hole on your device.
- If your device has anti-twist holes, ensure the retractable pins align with them. The pins will retract if not needed.
- Tighten the knurled thumbscrew clockwise until your device is securely fastened. For additional security, use the included Allen wrench in the securing hole to further tighten.

2. Adjusting the Crab Clamp
The crab-shaped clamp is designed for quick and secure attachment to various surfaces:
- Identify the surface you wish to clamp to (e.g., tube, table, tripod leg). The clamp accommodates diameters from 15 to 40 mm (0.6 to 1.6 inches).
- Loosen the T-handle screw on the crab clamp to open its jaws.
- Position the clamp around the desired surface. The built-in anti-slip pads will protect your equipment and enhance stability.
- Tighten the T-handle screw firmly until the clamp is secure.

Operating Instructions
1. 360° Ball Head Adjustment
The magic arm features a central wingnut that controls the articulation of both ball joints. This allows for smooth 360° rotation and precise device repositioning:
- To adjust the angle, loosen the central wingnut. This will allow the ball joints to move freely.
- Position your device to the desired angle and orientation.
- Tighten the central wingnut firmly to lock the ball joints in place, ensuring your setup remains stable.

Maintenance
- Cleaning: Wipe the product with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or abrasive materials.
- Storage: Store the magic arm and clamp in a dry, cool place away from direct sunlight and extreme temperatures.
- Lubrication: Periodically check the moving parts. If articulation becomes stiff, a small amount of silicone-based lubricant can be applied to the ball joints.
- Inspection: Regularly inspect all screws and connections to ensure they are tight and secure before each use.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Device twists or rotates after tightening. | Insufficient tightening of the thumbscrew; anti-twist pins not engaged. | Ensure the thumbscrew is fully tightened. If your device has anti-twist holes, verify the pins are properly seated. Use the Allen wrench for maximum tightness. |
| Clamp slips on surface. | Clamp not tightened enough; surface is too smooth or outside clamping range. | Tighten the T-handle screw firmly. Ensure the surface is within the 15-40mm diameter range. Clean the anti-slip pads if they are dirty. |
| Magic arm articulation is stiff. | Lack of lubrication; dust/debris in joints. | Clean the joints and apply a small amount of silicone-based lubricant. |
| Maximum payload exceeded. | Device is too heavy for the arm. | Ensure the total weight of the mounted device does not exceed 1.5kg (3.3lb). |
