Universal Size: Anti Vibration Pads fit furniture feet up to 1.97 inches in diameter and are designed to fit most front load and top load clothes washers and dryers. They are also compatible with beds, sofas, tables, refrigerators, and other household items. Quick & Easy to Install: These washing machine pads are stackable and require no tools for installation. Simply tilt your appliance onto a shock pad and repeat for each foot to level the unit. For stacked use, secure the two foot pads together with the included nuts and screws (4 sets provided), then place the anti-vibration pads under the equipment feet. Restore Peace & Quiet: The washing machine feet consist of two parts: a durable upper layer made of PP (polypropylene) and a lower layer made of natural rubber. These high-quality materials help reduce noise, dampen vibrations, and absorb shocks, protecting floors from scratches and abrasion. Waterproof & Easy to Clean: Made from premium waterproof materials, these anti-vibration pads help protect washers, dryers, and other appliances from water damage. They can slightly elevate appliances, making it easier to clean underneath, and help prevent debris buildup beneath the unit.
