The Hammertone Grip Plates 2.5kg are cast iron weight plates with a hammertone finish and built-in grip holes, making them easy to handle and load onto barbells and weight bars. The 2.5kg increment is ideal for micro-loading — making small, progressive increases to your lifts over time — which is one of the most effective strategies for long-term strength gains. Compatible with standard barbells and weight bars, they're a practical addition to any home gym or club weight room. Build your plate collection and keep progressing.
