A reach extender (or reacher, grabber arm, helping hand, trash picker, picker-upper, extended gripper, long arm gripper, extended reach grabber, grabber tool, litter picker, or caliper) is a handheld mechanical tool used to increase the range of a person's reach and grasp when grabbing objects. It has applications in waste management, assistive technology, gardening and outdoor work, and in some cases as a children's toy. It is chiefly used to pick items up off the ground, but can also be used to retrieve items from high shelves. The tool is commonly sold in hardware stores.
