High-Quality Door Reinforcement Hook—The cast aluminum alloy structure ensures durability and a long lifespan. The heavy-duty hooks can support 500 pounds (230 kg). The raised surfaces make them more robust/non-slip and, even in wet shoes, more sturdy and secure. Multifunctional Door Foot—1) Easier access to the roof; 2) The sharp end of the door tread can be used as a safety hammer; 3) When the stop is unstable in wet weather, it can be placed under the wheel to prevent it from slipping; 4) When your hands are full, the door steps can also be used as a temporary phone holder. The door frame is not damaged—the rotating hexagonal rubber base is designed to prevent paint damage at the connection points, and the thickened, high-density rubber wheels protect the frame from dents and scratches. This small, portable tool with a foldable hook takes up minimal space in the car and is very easy to use. It can be installed in your door frame in seconds. Easy roof access—simply hook the door
