Know before you buy
The overall length of 9.125" includes the entire structure of the arm, while the 8" socket-to-socket length refers to the distance between the center points of the two ball sockets. This measurement is most useful for calculating the actual reach of your mounting configuration.
This arm is specifically designed for 1.5" C size ball components. It will not fit smaller B size or larger D size RAM ball bases, so ensure your existing components are compatible with the C size standard.
The arm supports up to 4 lbs for standard use, such as in a vehicle or office setting. For heavy-duty applications involving high vibration or off-road use, the weight capacity is reduced to 3 lbs to ensure stability.
Yes, it is constructed from powder-coated, marine-grade aluminum, which is specifically designed to resist corrosion and withstand harsh outdoor environments, including saltwater exposure.
The central knob loosens the tension on both ball sockets simultaneously, allowing you to reposition your device freely. Once you have found your preferred angle, simply tighten the knob to lock the entire assembly firmly in place.
