The W4 37858 is a pack of two transparent suction cups with integral hanging hooks, designed to provide a quick temporary hanging point without drilling holes or using screws or adhesive. They are particularly useful in caravans, motorhomes, campervans, boats, bathrooms and kitchens. They attach to clean, smooth non-porous surfaces, such as glass, tiles and suitable smooth plastics, and can be removed and repositioned when required.
