Tri-Grip rubber-coated weight plates. These are Olympic standard weight plates with 2" holes. This is what you need at your home gym to keep the noise to a minimum. 
 
These plates have three easy grab handles strategically placed to make plate pickup and bar loading/unloading much easier. 
The center hub is lined with metal which makes it smooth to slide on the bar. 
The thick rubber coating encases the cast iron plate increases the durability, longevity and diminishes plate chatter, and protects the floors and equipment. 
 
The plates are perfect for in-home use, commercial setting, and school weight rooms.
