This configuration uses a regular suction cup attachment, so the arm can be mounted directly on glass, plexiglass, or another smooth surface such as a window. The short 1-inch ball arm keeps the setup compact and close to the surface, which is useful in cabins, vehicles, and inspection areas where space is limited. It offers a clean, removable mounting option with quick installation and easy repositioning. Compatible with any DURA Arms head or POS plate.
