Clamps onto any tubular bed frame, wheelchair frame, or other tubular frame with a diameter of 3/4 to 1" (1.9 to 2.5 cm). Most glasses or cups will fit into the plastic holder, even those with handles. It can also hold a beverage can or bottle. An 11" (28 cm) long flexible, chrome plated gooseneck makes positioning of the cup holder easy.
