ATX Competition Barbell Collars

The ATX Competition Collars are designed for the most demanding weightlifters and powerlifters. These 2.5 kg collars feature a large lever that can be securely tightened and allows for quick and easy plate changes. The inner side of the collars is equipped with a compression band that prevents damage to the barbell. The star-shaped twist ring ensures the collars can be tightened firmly against the weight plates for a secure fit without play.

What is a Collar?

What barbell collars are

Collars (clips) lock the plates onto a barbell’s sleeves so they can’t slide or rattle off — a safety essential, especially for pressing and Olympic lifts. The common types: cheap spring clips, quick lock-jaw / quick-release collars (the everyday favorite — fast and secure), and competition collars (precision-weighted, 2.5 kg each, for calibrated meets).

What to look for

A secure clamp that won’t creep under drops or high reps, quick on-and-off operation, and a fit for your bar’s sleeve diameter (standard Olympic is 50 mm). For most home gyms, a pair of lock-jaw-style collars is the right balance of speed, grip, and price.
