The Medline Deluxe Tub Grab Bar has a step-through clamp design that provides an unobstructed entry and exit path for better hand positioning. The tool-free installation has stainless steel components with rubber-lined pads that won’t mar your tub’s surface and provides better handling while in use. The grab bar adjusts to fit tubs 2.75″- 6.25″ (7-16 cm).
