The H-18 Magic Arm is a mounting kit for tablet computers, communicators, or ebooks, an adjustable ebook holder and a stand for a tablet computer designed for use by people with grasping, neurological or upper extremity disabilities, cerebral palsy or arthritis. The H-18 includes the Super-Clamp which allows clamping to wheelchairs, bedrails, desks or tables; and an iPad tablet holder without case or an adjustable tablet holder (ATH) for other devices or tablets such as the Auggie or Super-Auggie (see separate entries), Barnes and Noble Nook and Amazon Kindle. The user can select a standard, tall, or tall and wide ATH. The tablet can be removed from the holder, or the holder can be separated from the "Tipper" (adapter) by pressing the "Quick Connect" lever. The distance of reach is adjustable up to 24 inches. The H-18 features a small, incrementally adjustable lever/knob at the "elbow" that tightens/loosens all three joints of the Magic Arm.
