Abstract: Apparatuses and systems for mounting an adjustable arm for a peripheral device. The systems are configurable mounting systems for mounting an arm device. The systems comprise a set of components which may be configured to create a clamp mount, a wall mount, a “reverse” wall mount, or table or “flat” mount, a panel mount, and a slat mount. The components of the mounting apparatuses and systems all include a shaft holder for receiving the shaft of the arm apparatus. A variety of attachment configurations are provided to attach the shaft holder to a surface.
