Suction cup hook with large vacuum suction cup base 9cm diameter with self-adhesive gel, strong suction force for most smooth non-porous surfaces like glass, wood, metal, cars, etc. Load capacity of 15kg (30lb), can be used as a car luggage bungee cord for easy screw-free fixing of awnings, outdoor sail and camping. Lightweight, easy to carry and transport, easy to disassemble and reusable. Simply place the flat suction cup on a smooth, dry surface and operate the lever, which creates a very powerful suction cup. Note: Suction cups must be clean and dry before use and have a smooth, stain-free surface to ensure optimal adhesion. Unlike simple suction cups that only adhere to a surface or by pressure, our suction cups with added leverage create a better vacuum seal, so the hook stays on the surface longer. Versatile: Suction cups with 360-degree swivel hooks are perfect for camping enthusiasts, easy to carry when traveling, and suitable for blinds, car tents, sunroofs, apartments,
