The DG9038CA 3-Joint Mounting Arm with 1 AD4000 Quick Release Adapter from NOGA features a 1/4" threaded top and a 3/8" bottom. The arm is suitable for use with a wide range of cameras as it attaches easily via a standard 3/8"" and 1/4"-20 screw.

Supporting a monitor or camera light, the arm can be moved to the left or right of the lens, raised or lowered, and even tilted up or down to provide the clearest view or to get just the right angle for the job.  The arm comes with an integrated 1/4-20 AD4000 quick release adapter.   The adapter allows for fast removal of accessories or arm by a pull to release connection.
