Secure, Fast-Locking Collars for 50mm Bars

Keep your plates firmly in place during every lift with this 1 pair of 50mm spinlock barbell collars. Designed for professional, high-quality and reliable ecommerce standards, these lock clips provide a strong, consistent hold on standard Olympic bars so you can train with confidence and minimal downtime between sets.

Each collar is engineered to fit 2" (50mm) bar sleeves, including threaded, smooth, straight, EZ curl and tricep bars commonly found in home and commercial gyms.
