Lock-Jaw OLY 2 Olympic Barbell Collar - Fast Secure Clamp

Our review of the Lock-Jaw OLY 2 Olympic Barbell Collar finds it best for lifters who need a fast, rock-solid solution for changing plates and keeping them secure during heavy lifts. The bottom line: this collar's over-sized quick-release latch and reinforced composite body deliver a level of holding power and durability superior to spring-style clips, making it a smart choice for regular training, HIIT sessions, and competition warmups where speed and reliability matter.

Key Features

• Lifetime warranty: The genuine Lock-Jaw collar includes a lifetime warranty that offers long-term reassurance for frequent use.
• Reinforced resin construction: Advanced composite reinforced resin gives the collar high impact resistance and overall durability for repeated drops and heavy loads.
• Secure hold: The design prevents rattling and sliding so plates stay clamped during deadlifts, squats, and Olympic lifts, maintaining consistent bar balance.
• Quick one-handed operation: The over-sized latch makes it easy to lock and unlock the collar with a single hand for fast weight changes between sets.
• Dual-bar fit: The collar fits both 2in and 50mm bars, covering the two most common Olympic and utility bar sizes for versatile gym use.

Who It's For

The Lock-Jaw OLY 2 is ideal for serious lifters, coaches, and gym owners who swap plates frequently and need a collar that stays put under high loads and during dynamic movements. It suits powerlifters, Olympic lifters, and anyone using bumper plates for cleans, jerks, and overhead work.
