These 28mm Shower Chair Rubber Tips / Ferrules fit most standard shower chairs. The pole width will need to be 27mm to 29mm. The ferrules have a 58mm base which provides extra stability, especially when gripping to wet area flooring and showering.
It is recommended to change the tips of your shower chair every couple of years or when noticeable deterioration is visible. Using old or worn away tip on your shower chair can hinder the integrity of the frame, and therefor its safety. If even 1 of the 4 tips is damaged, it can cause the chair to be unstable. These are sold in a pack of 4.
