Lock-Jaw Barbell Collars PRO 2 2"/50mm Olympic Bar Collars, Black, Quick-Release Lever, Elastomer Pads

Lock-Jaw PRO 2 barbell collars secure 2" Olympic sleeves with a fast, single-handed clamp that prevents plate movement without harming bar finishes.

The Lock-Jaw PRO 2 is a premium pair of 2"/50mm barbell clamps engineered for lifters who need dependable plate retention, quick transitions, and long-term durability. These clamps combine a patented quick-release lever, reinforced composite body, and internal elastomer pads so they stay tight under heavy sets while protecting specialty bars such as Cerakote or axle bars. Ideal for home gyms and commercial facilities alike, the PRO 2 is designed to reduce interruptions, rattle, and plate slippage.

How do these collars keep plates from sliding during lifts?

The PRO 2 uses a press-fit design and an oversized quick-release lever to create consistent clamping force across the sleeve. Internal elastomer pads increase friction without scratching the bar finish, so weights remain locked in place through dynamic movements and drops.

• Patented lever provides strong, repeatable clamp force.
• Elastomer pads grip sleeves gently but firmly.
• Composite body resists deformation under impact.

Will these clamps damage my Cerakote or specialty bars?

No. The PRO 2 includes specially shaped internal pads that protect bar coatings while securing plates. That means you can use these clamps on Cerakote, axle, log, and other specialty bars without worrying about abrasions or finish wear.

• Soft internal pads safeguard bar surfaces.
• Designed to fit all standard 2" Olympic sleeves.
• Engineered for compatibility with specialty bars and finishes.

How quickly can I change weights between sets?

The oversized quick-release lever enables one-handed operation so you can unclip and reclamp in seconds. After a short break-in period the mechanism runs smoothly, letting you spend less time fiddling with hardware and more time training.

• One-handed open/close lever speeds transitions.
• Break-in improves lever action for consistent use.
• Compact footprint clears racks and collars easily.

How durable are Lock-Jaw PRO 2 clamps under heavy gym use?

Constructed from reinforced nylon resin, the PRO 2 resists impacts and repeated drops better than ordinary metal clamps that can bend or mar bars. The composite structure preserves clamping geometry so the collars maintain holding power over time.

• Reinforced composite resists cracking and bending.
• Built for high-impact and frequent commercial use.
• Backed by a lifetime warranty and patented design.

Who is this for? The Lock-Jaw PRO 2 is made for serious lifters, coaches, and facility owners who demand fast plate changes, secure retention, and bar protection. It suits anyone using 2"/50mm Olympic sleeves—especially those with specialty bars or high-traffic gyms—who want a maintenance-light, long-lasting solution for safer, quieter lifts.
