★Wondering how to keep rugs from slipping? This is a problem that troubles many people. To address it, we provide a new material which works as a rug gripper. This method uses VACUUM TECH design which grips all types of floors firmly and easily. ★Design Principle. This product can easily be glued under any rug. The side facing the floor features tiny suction pores. These pores utilize the VACUUM TECH principle in which whenever pressure is applied from the top, air escapes and creates a low-pressure region within the cups. This produces an adhesive effect, which keeps your rug in place."DOES NOT WORK FOR RUGS ON CARPET FLOORS"★Advantages. The anti-curling rug gripper is less than 1/10 inch thick and inconspicuous after installing. Suction technology firmly sticks to the floor without causing marks or damage, and the gripper easily peels off the floor. It is convenient to wash, as you won’t have to separate it from your carpet for cleaning. The rug tape adds extra comfort underfoot owing to the slightly bouncy nature of suction technology.★Components. This package includes 4 pieces. Each piece is square in order to increase the surface area in contact with the floor. That leaves your kitchen, bathroom, and hallway much more secure. You can even use them outdoors to prevent slipping and flatten corners. ★Money Back. A 1-YEAR 100% Money Back accompanies this product. This ensures that your rug remains securely in place, and helps to prevent accidental slips and falls. If you are not 100% satisfied, send us a message and we will make a refund without any question.
