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 appliances. 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 using the included nuts and screws (4 sets provided), then place the anti-vibration pads under the appliance feet. Restore Peace & Quiet: The washing machine feet consist of two parts: a durable upper layer made of PP (polypropylene) and a bottom layer made of natural rubber. These premium materials effectively reduce noise, dampen vibrations, and absorb shock, helping protect floors from scratches and abrasion. Waterproof & Easy to Clean: Made from high-quality waterproof materials, these anti-vibration pads help protect washers, dryers, and other appliances from moisture damage. They slightly elevate the appliance, making it easier to clean underneath, and help prevent debris buildup beneath the unit.
