Designed with a medium depth diamond knurled surface and sleeves, the CAP 7' Olympic Weight Bar swivels at the most delicate touch to prevent the bar from warping. Its medium depth knurled surface helps to provide friction and ensure that your grip is secure. This helps to reduce pressure on your wrists when lifting weights. It is made of wear-resistant steel for durable performance, ensuring that it will last for years to come. The Olympic weightlifting bar can fit 2" hole plates and has a weight capacity of 500 lb, making it appropriate for just about every lifter. This strength training equipment is a great addition to your home gym.
