USA Aluminum Collars 2.0

The Rogue USA Aluminum Collars 2.0 build on the proven performance of our original USA Aluminum Collars with targeted upgrades to durability, grip, and ease of use. CNC machined in the USA from aircraft-grade 6061 billet aluminum, each collar measures 1.5” wide and is compatible with all standard Olympic barbell sleeves. Designed for serious training environments, they deliver consistent plate security without excessive bulk or weight.

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.
