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-loading clothes washers and dryers. They are also compatible with beds, sofas, tables, refrigerators, and other household appliances. Quick and 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 and Quiet: The washing machine feet consist of two parts: a durable upper layer made of polypropylene (PP) and a bottom layer made of natural rubber. These high-quality materials effectively reduce noise, dampen vibrations, and absorb shocks, helping protect floors from scratches and abrasion. Waterproof and Easy to Clean: Made from premium 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.
