Lock-Jaw Barbell Collars PRO 2 barbell collars for 2"/50mm Olympic bars, All Black, quick‑release composite

Lock-Jaw PRO 2 barbell collars are a pair of high-holding, quick-release clamps engineered to secure 2"/50mm Olympic sleeves for safer, faster plate changes.

Whether you train at home or in a commercial facility, the Lock-Jaw PRO 2 replaces noisy, loose clips with a refined composite clamp that grips plates without marring the bar. Designed from reinforced nylon resin and fitted with internal elastomer pads, these clamps combine stronger holding force, rapid one-hand operation, and compatibility with specialty bars like axle and trap/Log bars. The patented lever mechanism is tuned for easy engagement and a short break-in for smooth repeat performance.

How do the PRO 2 collars stop plates from sliding and rattling?

The PRO 2 delivers roughly 50% more clamping force than ordinary spring clips by pairing a robust composite body with precision elastomer pads on the interior. That combination maintains a snug fit on Olympic sleeves under dynamic loads and repeated drops.

• Proprietary reinforced nylon resin resists deformation under impact
• Internal elastomer pads protect finish while increasing grip
• Engineered geometry reduces movement and eliminates rattle

How quickly can I swap plates during workouts?

The oversized quick-release lever is designed for one-handed operation so you can clamp or remove the collars in a second. After a short break-in the mechanism runs smoothly, speeding up superset transitions and timed circuits.

• Patented lever for fast release and secure lock
• Ergonomic shape gives confident one-hand control
• Consistent operation once lever bedding-in is complete

Will these collars damage my bar’s cerakote or specialty finishes?

No — the Lock-Jaw PRO 2 includes specially formulated internal elastomer pads that grip without scratching or wearing away delicate finishes. They’re safe for all 2" Olympic sleeves, including specialty bars that often have premium coatings.

• Soft elastomer contact points preserve cerakote and chrome
• Even pressure distribution avoids concentrated wear spots
• Compatible with axle, log, and safety squat specialty bars

How durable are these collars compared with metal clips?

Built from a reinforced composite engineered for high-impact use, the PRO 2 stands up to heavy drops better than standard metal clamps that bend or loosen. The materials and construction are optimized for long-term performance in both home and commercial settings.

• Reinforced nylon resin resists cracking and bending on impact
• Composite design avoids permanent deformation common with metal clips
• Backed by a Lifetime Warranty and U.S. Utility Patent

Who is this for: The Lock-Jaw PRO 2 is ideal for athletes and gym owners who want reliable, fast, and bar-friendly collars for 2" Olympic sleeves. If you switch plates frequently, use specialty bars, or need a quiet, secure clamp for heavy lifts, these collars are built to deliver pro-level performance and durability.
