The grab bar accessory can be used in two ways. 1) installed between two Wonder Pole Premiums, or between one Wonder Pole Premium and the wall. Installation will vary depending on how the accessory is used. If attached to a wall, it is required to drill the grab bar into a wooden wall stud. If used between two Wonder Pole Premiums, the grab bar attaches by wrapping the clamp around the poles and tightening with the included Allen wrench. The grab bar can be placed at any height on the pole for optimal positioning. For more information or to watch a tutorial video, visit the product’s support page.
