Lock-Jaw OLY 2 Olympic Barbell Collar - Secure Quick Release

In this review the Lock-Jaw OLY 2 Olympic Barbell Collar proves itself as a simple, durable solution for lifters who need a fast, reliable way to lock plates in place. Designed for Olympic-style bars and heavier training, the collar's single biggest advantage is its hold: no rattling or sliding plates during heavy sets. The review focuses on real gym use, highlighting the composite reinforced resin construction, one-handed quick release latch, and compatibility with both 2' and 50mm bars, making it a practical upgrade from spring clips for most strength athletes.

Key Features

• Lifetime Warranty: A genuine Lock-Jaw product backed by a lifetime warranty gives confidence in long-term use and replacement if anything fails.
• Reinforced Resin Construction: Advanced composite construction provides unmatched durability without the metal-on-metal noise of steel collars.
• Unrivaled Holding Power: The clamp secures plates tightly so there is no rattling or sliding during heavy lifts, drops, or dynamic movements.
• Quick One-Handed Operation: The oversized quick-release latch lets you lock and unlock the collar with one hand for fast weight changes between sets.
• Dual Bar Fit: Designed to fit both 2' and 50mm bars, it works with most Olympic barbells and standard competition setups.

Who It's For

The Lock-Jaw OLY 2 is ideal for strength athletes, CrossFitters, and home gym owners who need a dependable collar that installs quickly and stays put under heavy loads. It suits anyone swapping plates often during training, and lifters who dislike the slippage and noise of spring-style clips will appreciate the secure hold.

It is less necessary for users who rarely change weights or only lift light loads with low plate movement; those with a strict preference for traditional steel collars might also prefer a different aesthetic, though functionality here favors composite construction.
