Installation (Adhesive Pad Version): Clean the wall surface thoroughly with a dry cloth. Apply the supplied adhesive pads in a wavy pattern. Press the hook firmly against the wall, holding it in place for 3-5 minutes. Allow the adhesive to cure for 48 hours before use. Installation (Screw Mount Version): Drill a hole (using a 6mm drill bit) at least 5cm deep, perfectly perpendicular (90) to the wall. Gently tap the included plastic wall plug into the hole until it sits flush with the wall surface. Screw the provided screw into the wall plug evenly.
