1. Multi-directional rotation: Connect to 1.5-inch ball components for near-infinite adjustment to achieve the best viewing angle. Use the top and bottom knobs to adjust the direction of the 1.5" ball adapter (not included). The center knob adjusts the direction of the two arms. Ratchet arms provide additional adjustable directions and prevent center point from rotating in harsh environments.
2. EXCELLENT COMPATIBILITY - This arm has a total length of 8.1 inches (206mm) and can be connected to any 1.5 inches/C/38mm ball components, including mounting bases and device holders. All of our components are compatible with RAM mounts as well as 1.5" ball systems from manufacturers such as Arkon and iBolt.
3. Sturdy Material The double socket swivel arm is made of high-strength composite materials, which makes it sturdy but lightweight, which effectively reduces the leverage and vibration of the device.
4. HIGH LOAD CAPACITY - The double socket swivel arm has a load capacity of up to 10.5 lbs when standing and 3 lbs when in motion.
5. Rotation Angle: Suitable for 1.5 inch C size ball base. The arm has a 360° rotation point in the center and the connected swivel joint can rotate 180° back and forth. The rubber ball and bushing on both ends, along with a central pivot point, provide unparalleled adjustability.
