1/2PCS Safety Grab Bars for Bathtub Bathroom Shower Suction Cup Grip Handle Installation tips: It is recommended to adsorb on smooth tiles and glass. Wipe the tiles and glass with a damp cloth before use. It can be adsorbed directly without drying. The armrest should be adsorbed again after a short adsorption, as the air penetrates slowly after a long time and the suction cup can no longer hold it. Before you press the locking button, press the suction cups each so that the suction cups come into contact better with glass and tiles. If you cannot vacuum it for the first time, because the middle part does not completely touch the glass and the tiles sususuit it Please several times. After the suction cup is completely in contact with the glass and tiles, it can be sucked in.
