About PRx Cast Iron Olympic Plates

You need plates that just work—set after set. PRx Cast Iron Olympic Plates deliver straightforward durability and accurate sizing for barbell training. With a 2" (50.6 mm) collar opening, they slide cleanly on Olympic bars and stay tight during work. The dark gray painted finish handles garage life and gym volume without fuss.

Build your stack with the right sizes

Training flows when you can load exactly what you need. This lineup covers the essentials from 2.5 to 45 lb, including the often-missed 15s and 35s for smarter jumps. The diameters and widths are balanced so you can stack plenty on the bar without fighting space, and the edges are easy to grip for quick changes. Whether you’re chasing a total or training the basics, these plates keep the math simple and the work steady.

• Range: 2.5, 5, 10, 25, 35, 45 lb

Consistent fit for smooth sessions

Loose or tight plates slow you down. These cast‑iron discs are sized to seat well on standard sleeves, reducing rattle while still sliding on and off quickly. The painted finish resists rust and wipes down easily after chalky sessions. Keep a pair near each station and switch loads without disrupting your pace or your focus.

• Painted dark gray for corrosion resistance
• Clean edges for secure handling
• Durable for daily training
