Lock-Jaw Olympic Barbell Collars designed with a quick-locking mechanism to secure weight plates.
They are constructed from durable plastic and designed to fit standard 2-inch (50mm) Olympic bars.
The collars are typically sold in pairs and feature a rubber lining to protect the barbell sleeve and provide a secure grip.
They are suited for various exercises including deadlifts, squats, and bench presses to prevent plates from sliding.
