This RomHaus double socket arm is a game-changer for mounting your gear! Made from durable aluminum alloy, this 2.36-inch extension arm can handle tough outdoor conditions with high impact and vibration. It connects to any 1-inch/25mm ball joints, making it super versatile for creating custom mounts for your GoPro, GPS devices, phones, or tablets. The knobs on the side let you quickly tighten and secure your setup - no tools needed! Whether you're mounting it to a suction cup, clamp, or drilling base on your bike, motorcycle, truck, or other vehicle, this arm gives you that extra reach and flexibility to position your devices exactly where you need them. One important note - because it's a shorter arm, there's no spring inside to hold the two halves together, but once you twist it on your ball joints, it stays firmly in place. This little accessory opens up so many possibilities for mounting solutions in your vehicle or workspace!
