No vibration, noise and walking - Anti walking pads provide stable support for large electrical appliances (including washing machines and clothes dryers), reduce vibration, noise and slip, and achieve stable and quiet operation. Shock absorption and textured shock pads effectively eliminate "walking" equipment. This set includes four pads that cover every corner of the washer or dryer. Good quality - this product can prevent vibration and machine walking. We developed this product through direct experiments. Although the others are made of rubber, we added plastic materials so that these pads can be combined. Therefore, it is possible for the machine to level the feet. Easy to install - no tools or dirty adhesive required. Just lift each corner of the machine and slide the sound absorbing pad into place. For convenience, our padding design fits all standard four leg washers and dryers. Our rubber feet stick easily. Do not skip the leveling machine! Specifications; The diameter of the lower wall is 8cm
