This GyroVu Heavy-Duty 7" Articulated Arm Mount comes with a jaw clamp and a two-part quick release attachment. The top plate of the quick release screws onto your monitor via a 1/4"-20 interface, and you can then quickly attach or remove your monitor, releasing it at the pull of a slide button. You can also mount LED lights and other devices. The jaw clamp can grip onto gimbal tubes, tripod legs, table edges, and other objects matching its clamping range of 0.5 to 1.5". It's secured by a T-handle and is rubber-padded to prevent twisting and scratching.
The articulating arm is 7" long fully extended and has a native 1/4"-20 stud on each end, to which the clamp and quick release secure. The center mechanism uses rosettes for locking the arm, preventing slipping due to wear or insufficient tightening. A wingnut in the center tightens all three joints of the arm at the same time.
