The Force USA XCalibur Locking Collars use a self-locking cam-lock design that clamps down instantly and holds — no threading, no spinning, and no re-tightening mid-set. Built for competitive lifting and serious training, they're drop-tested for durability and machined to keep their grip through years of hard use. Key Features Self-locking cam-lock mechanism for instant lockdown Aircraft-grade aluminum construction with reinforced nylon components Drop-tested over 10,000 times Diamond-knurled exterior for secure grip, even with chalked hands Fits Olympic bars, specialty bars, and Smith machines Description Unlike collars that need to be screwed or clipped into place, the XCalibur Collars use a cam-lock lever that clamps tight against the sleeve the moment you flip it closed, creating even pressure around the entire sleeve so plates can't migrate or spin loose mid-set. The aircraft-grade aluminum body is reinforced with nylon components and finished with a diamond-knurled exterior that mirrors barbell grip patterns, keeping it secure in your hand even when chalked up. Built-in neodymium magnets let you stick them to a rack, plate, or any steel surface between sets. Available in Stealth Black, Raw Silver, and Competition Blue.
