Key benefits - VACUUM TECH design grips hard smooth floors firmly and easily, helping rugs stay in place on suitable surfaces. - Ultra-thin and unobtrusive: less than 1/10 inch thick and virtually invisible after installation. - Gentle on floors: suction technology adheres without leaving marks or damage; the gripper can be peeled off the floor when needed. - Easy maintenance: can be washed and furniture/cleaning tasks won’t require removing the rug. - Adds underfoot comfort: the slight cushioning from the suction-based grip provides a bit of bounce. Important notes on compatibility and limitations - Works on hard smooth floors; not suitable for rugs on carpeted floors. - Not all rugs are compatible: does not work with rubber backed rugs, jute rugs, or rugs with fluffy/backing textures. Please check rug type before use. - The adhesive surface cannot be peeled once affixed to the rug. - Intended for under-rug use; designed to remain hidden underneath while delivering secure grip. How it works - The underside facing the floor features tiny suction pores that employ VACUUM TECH. - When pressure is applied from the top, air escapes from the cups, creating a low-pressure region that produces an adhesive effect and helps keep the rug in place. Design and installation details - Thickness: less than 1/10 inch; designed to be inconspicuous after installation. - Installation method: the product is designed to be glued under the rug. - Floor-friendly: suction-based grip holds the rug without leaving marks or damage to the floor. - Removal: the gripper easily peels off the floor when needed. - Cleaning: convenient to wash since you won’t have to remove the rug for cleaning. Package contents and specifications - 16 pieces included. - Each piece size: 3.9 inches x 3.9 inches. - Shape: square to maximize surface area contact with the floor. - Applications: suitable for securing rugs in kitchens, bathrooms, and hallways; can also be used outdoors to prevent slipping and to flatten corners. Use scenarios - High-traffic areas: in kitchens or entryways, secure area rugs on hard floors to prevent curling and shifting. - Hallways: keep runner rugs flat and in place, reducing edge lifting in busy passages. - Outdoor or semi-outdoor entrances: use to prevent slipping and to keep rug edges flat near doors and thresholds.
