The Force USA® Aluminum Olympic Lock Collars (pair) are high-quality aluminum safety lock collars for Olympic barbells. With a sturdy locking mechanism, lightweight aluminum body, and reliable holding force, they are the premium solution for securely securing weight plates.

Premium aluminum fuse

Unlike simple plastic or rubber clamping rings, aluminum lock collars offer significantly greater holding force and durability. Aluminum is lightweight, corrosion-resistant, and extremely durable—even under intensive, continuous use, the collars remain precise and secure.

Locking mechanism for maximum security

The locking mechanism securely clamps the barbell sleeve in place with a precise lever action. The hold is strong enough to prevent the weight plates from slipping, even during uncontrolled movements.

Quick and easy to use despite a secure clamp

Despite their strong clamping force, the collars can be opened and closed quickly. The lever mechanism allows for tool-free operation in seconds—perfect for frequent weight changes.
