1. Multi Directional Rotation: Connect to 1.5 inch ball components for nearly infinite adjustability to achieve the best viewing angle. Use the upper and lower knobs to adjust the direction of the 1.5 inch ball adapter (not included). The center knob adjusts the direction of the two arms. The ratchet arms provide additional adjustable directions and prevent the central point from rotating in harsh environments.
2. Excellent Compatibility: This arm has a total length of 8.1 inches (206 mm) and can connect to any 1.5 inch/C sized/38 mm ball component, including mounting bases and device holders. All our components are compatible for as well as the 1.5 inch ball systems from manufacturers like for Arkon and for iBolt.
3. Sturdy Material: The double socket swivel arm is made from high strength composite materials, making it sturdy yet lightweight, effectively reducing device leverage and vibration.
4. High Load Capacity: The double socket swivel arm has a load capacity of up to 10.5 pounds when stationary and 3 pounds when in motion.
5. Rotational Angles: Suitable for 1.5in C size ball base. The arm features a 360° rotation point at the center and the connected swivel joint can rotate back and forth by 180°. The rubber ball and socket at both ends, along with a central pivot point, provide unparalleled adjustability.
