Uni Strength collars: technical specifications

What makes the difference

• A single piece of aluminium. No two halves joined together as on plastic collars: nothing works loose or breaks.
• A grip that lasts. The lever locks the collar firmly on the bar and the tension does not slacken over time. The plates stay in place, even when the bar is dropped.
• 3 built-in magnets. The collars stick to the rack uprights between sets: no more collars lying on the floor.
• An ergonomic shape. The 6 lugs give a good grip and the lever works with one hand.
• An anodised finish. The black finish resists wear and keeps its look over time.
• A rubber lining. It adds grip and protects the bar sleeves.

What are barbell collars used for?

Barbell collars lock the weight plates onto the bar so they cannot slide during the lift. This makes the exercise safer, protects your equipment and gives greater stability during explosive or asymmetrical movements. They are essential for squats, deadlifts, bench presses and snatches.

Why choose a magnetic aluminium collar?

Compared with standard plastic collars, aluminium is more durable, stronger and more impact-resistant. The magnets let you attach the collars directly to the rack, so they no longer lie around on the floor or go missing. You gain convenience, faster set-up and a tidier home gym or training room.

These Uni Strength collars were designed specifically for regular, intensive training. Their quick-lock system, light weight, wear resistance and scratch-resistant inner lining make them perfectly suited to daily use, even with heavy loads.
