Olympic plate HMS BLACK BUMPER 25 kg BBR25 The BBR HMS Olympic Plate, covered with the highest quality rubber, boasts a perfect cast, aesthetic finish, and a special profile that prevents rotation on the bar. The plates are made of the highest quality materials. They are covered with a special, thick rubber that absorbs every impact, preventing damage to the floor in the event of a fall. BBR HMS plates achieve a Shore A hardness rating of 75 to 96, depending on their weight. This means they are significantly more durable than cheaper, rubber-coated plates available on the market. Each plate is calibrated for weight and dimensions. This means the disc's weight must be within +0.5% and -0.5%. The inner diameter is designed to fit Olympic bars. Precise craftsmanship ensures stability during intense training. The plate's sleeve is made of stainless steel, making it easier to load and unload the weight from the barbell. Additionally, it is an element that keeps the load stable on the bar. Specification material: rubber-coated stainless steel weight: 25 kg inner diameter: 51 mm outer diameter: 450 mm width: 84 mm Comments: not intended for commercial use 24-month warranty
