Cast iron weight plates set 4×5 kg with 31 mm bore and handles, Rebel (RBA-2134)

Set of four 5 kg cast iron weight plates (total 20 kg) with a 31 mm bore and integrated handles. These plates are intended for use with Olympic-style bars and home gym bars that accept 31 mm sleeves. The cast iron construction offers durable resistance for free weight training and plate-loaded equipment while the molded handles make loading, carrying and small positional adjustments easier.

Advantages

The set delivers a compact 20 kg total allowing incremental load increases with 5 kg discs. Cast iron material provides long-term durability and consistent performance. Integrated handles reduce the need for additional tools when changing plates and improve safety when carrying or racking weights. The 31 mm bore is compatible with common Olympic/home gym bar sleeves, ensuring straightforward fit and secure placement during lifts.

Suitable for

• Barbell training: squats, deadlifts, bench press with 31 mm sleeve bars
• Home gym setups and small commercial gyms with standard sleeves
• Plate-loaded machines that accept 31 mm diameter discs
• Strength training routines requiring incremental 5 kg increases

When it may not be suitable

The plates are designed for bars with a 31 mm sleeve; they will not fit bars with smaller or larger sleeve diameters without an adapter. Because these are solid cast iron discs, they are not coated with rubber and may cause more noise and floor wear if used without protective mats or pads. The set provides a total of 20 kg, which may be insufficient for advanced lifters seeking heavier single-plate increments.

Key specifications

• Weight per plate: 5 kg
• Total set weight: 20 kg
• Bore diameter: 31 mm
• Material: cast iron
• Design feature: integrated carrying handles

How to use

Place the plates onto a compatible bar sleeve (31 mm diameter) and secure them with appropriate collars or clips before performing exercises. Use the integrated handles to lift and slide plates onto the bar or to carry them between storage and workout area. When loading multiple plates, distribute weight evenly on both sides of the bar and ensure collars are tightened to prevent movement during lifts. Store plates on a rack or vertical post to keep them accessible and to reduce floor contact.

What to consider before purchase

• Confirm your bar sleeves accept 31 mm bore plates
• Decide if cast iron (no rubber coating) suits your noise and floor protection needs
• Check whether a total of 20 kg meets your progression requirements
• Plan for secure collars or clips compatible with your bar

Usage recommendations

Use protective flooring or a mat when placing or dropping plates to protect the floor and reduce noise. Pair these 5 kg plates with smaller increment plates if finer progressions are needed, and regularly inspect handles and bore areas for wear to ensure safe operation.
