1" center hole, dedicated to home barbells, a whole piece of solid cast iron, anti-bending and anti-cracking, odorless and durable indoors, optional 2.5-45 lb, pound/kilogram dual marking

• 1" standard center hole: Designed for home use with a 1-inch standard barbell, it is firmly installed without shaking or falling off.
• A whole piece of solid cast iron: cast in one piece without filling, anti-bending and anti-cracking, can withstand high-intensity repeated impact, and is not easy to deform for life.
• Enamel anti-rust coating: baked and cured environmentally friendly paint surface, sweat-proof, moisture-proof and odor-free, it remains as bright as new after long-term indoor use.
• Precise dual-scale marking: each piece is clearly laser-engraved with pound & kilogram values, weight can be identified at a glance, and training and changing pieces are more efficient.
• Full specification pairs are available: 2.5 / 5 / 10 / 25 / 35 / 45 lb six weights, sold in pairs, free combination, to meet the strength needs from beginners to advanced.
