1. Made of high-quality ABS material, it is strong and durable, with a load capacity of 7.5 kg, providing stronger suction than traditional suction cups. The suction cup has a vacuum locking ring, which effectively prevents it from releasing air pressure due to tension and maintains a firm vacuum. Warning: The weight must not exceed 15 kg load capacity, otherwise it will fall. 2. The sturdy plastic handle, with its textured surface underneath, prevents your hands from slipping, even in wet conditions, providing safety protection for the bathroom, bathtub, and shower. Note: Do not force the handle to rotate or tear it. The marks \"OPEN\" and \"CLOSE\" are located above the rotating suction cup. Clockwise rotation locks the handle, meaning it is closed. 3. Powerful suction cup handles, wall-mounted suction cup handles for shower rooms, sliding door handles and strong suction cups for toilets and bathrooms, refrigerator door and drawer handles, glass door cabinets, pressure adhesive handles, bathroom handles and suction cup handles for showers. 4. Easy to install and remove; no tools required. It is lightweight and compact, so you can take it with you when traveling and easily install it in a hotel room or guest bathroom. Just press down the locking latch to secure the handle upwards. The handle can be securely attached to any flat, non-porous surface. 5. Portable support handle; the suction cup's vacuum pressure provides excellent grip, making it more convenient to open sliding doors/windows. Can be used on any flat surface without holes. It can only be installed on any flat, smooth surface, including tiles, glass, metal, plastic, etc. Please note: do not use on rough or uneven surfaces!!!
