Lock-Jaw One

Lock-Jaw One

The Lock-Jaw One features a solid injection molded nylon frame and thick molded pressure pads, making it the most durable standard collar available. The single-action cam lock securely clamps the collar and the quick latch is easy to use with small hands. Rubber compression pads prolong the life of the chrome bar coatings.

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.
