Wondering how to keep rugs from slipping? This is a problem that troubles many people. To solve this, we offer a new material that works like a rug gripper. Our solution uses vacuum technology to securely hold rugs on all types of hard, smooth floors. Note that it won't work for rugs on carpeted floors. It also won't work for rubber-backed rugs, jute rugs, or lint-backed rugs. Principle: This product can be easily glued under carpets. The side facing the floor features small suction pores. These pores, according to the vacuum technology principle, are used by the vacuum cleaner bag whenever pressure is applied, allowing air to escape and creating a low-pressure region within the cups. This creates an adhesive effect that holds your rug in place. Advantages: The anti-curling rug gripper is less than 1/10 inch thick and less noticeable after installation. Suction technology adheres firmly to the floor without staining or damaging it, and the gripper easily grips the floor. It's easy to clean, as you don't have to separate it from your rug for cleaning. The carpet tape adds extra comfort underfoot thanks to the slightly elastic nature of the suction technology. Components: This package contains 4 pieces. Each piece is square to increase the area in contact with the floor. This makes your kitchen, bathroom, and hallway much safer. You can also use them outdoors to prevent slipping and smooth out corners.
