Primiz Auto-Lock Olympic Collars

The Primiz 50mm Twist Lock Collars feature a quick-locking twist and a premium gripping surface to ensure safety and security from falls and drops. Slim, light, and durable, the Primiz 50mm Twist Lock Collars are designed for use with all 50mm (2”) weight lifting bars.

Slide on. Auto‑lock engages. Plates don’t move — not a millimeter. Engineered for lifters who need speed, security, and zero compromises: clamp down between sets in one motion, release just as fast, train without re-adjusting your bar.
