How to use

Slide the plate onto a compatible 25 mm bar sleeve until it rests against the collar or existing plates. Secure plates with appropriate collars or clips before performing exercises. Use matched pairs or evenly distribute weight on both ends of the bar to maintain balance. When changing plates, remove collars first and replace them after repositioning weights to ensure safe lifting conditions.

Usage recommendations

Inspect the plate periodically for cracks or severe corrosion; replace if structural damage is found. Keep contact surfaces dry and avoid dropping plates from overhead to preserve finish and integrity. Use appropriate collars to prevent lateral movement during lifts and store plates on racks or stands to protect edges and maintain a safe training area.
