Twelve cast iron plates are included in total - four at 2.5kg (14cm diameter), four at 1.25kg (12cm diameter) and four at 0.5kg (10cm diameter) - bringing the total plate weight to 20kg. All plates share a 3cm centre hole to fit the bars securely, held in place with spinlock collars. Bars feature an anti-slip knurled grip section, and the whole set is finished in black. A carry case is included for storage and transport. Straightforward, accurately specified equipment for anyone building a home gym.
