This 255 lb Hampton Olympic Grip Urethane Plate set uses an advanced design which makes them more functional, safe to use, and attractive. Each plate is fully coated in high quality urethane which is non-porous, and therefore easier to clean, more hygienic, and longer lasting than other plate materials. This set is designed with steel hubs for smooth loading and unloading. Each plate above 5 lb uses a generously sized set of grips to allow for easy transfer of plates, and helps prevent the user's fingers from being pinched between plates. Trying to pry a classic style 45 lb plate off the floor used to be a laborious routine, but the HOG urethane plate uses a unique design that makes picking up and moving plates a breeze. Both the structural integrity and the urethane coating of each plate is warranted for 5 years, making this the premier set for any home or commercial setting wanting a good-looking, high quality, hygienic, and durable plate set.
