A. Universal Size: The anti-vibration pads are suitable for furniture feet with a diameter of up to 1.97 inches and are designed for any front-loading or top-loading washing machines and dryers. They are also compatible with beds, sofas, tables, refrigerators, etc. B. Quick and Easy Installation: The washing machine pads can be stacked and are easy to install. Without stacking, no tools are required. Simply tilt the appliance onto the shock-absorbing pads and repeat the operation to keep the appliance level. When stacking, fix the two pads with nuts and screws (4 nuts and screws are provided). You can place the anti-vibration pads under the feet of the equipment. C. Restore Quietness: The washing machine pads consist of two parts. The upper layer is made of polypropylene (PP), and the lower layer is made of natural rubber. The materials can effectively isolate noise, reduce vibration and absorb the impact force generated by the equipment, protecting the floor from wear and scratches. D. Waterproof and Easy to Clean: The washing machine anti-vibration pads are made of waterproof materials, which can prevent washing machines, dryers and other appliances from being damaged by water corrosion. They can raise the height of the appliances, making it convenient to clean the garbage under the appliances and preventing garbage from accumulating at the bottom.
