The product is 37.6 inches long and suitable for doors no wider than 2.16 inches. Made of flexible PVC material, it is easy to bend and cut to fit the size of your door. The U-shaped design makes installation quick and easy—just measure the length of the bottom of the door, cut the seal to size, and slide it into place. It effectively seals the gap between the bottom of the door and the floor, blocking debris and the ingress of cold and warm air. This significantly enhances indoor comfort and insulation while reducing energy consumption. Additionally, the seal can block noise and light, providing a quiet and dark environment for a good night's sleep. Suitable for interior doors in various settings, including homes, apartments, hotels, and offices. Note: Not suitable for doors with thresholds.
