DMoose Barbell Clamps

DMoose’s Olympic Barbell Clamps are a budget quick-lock collar for standard 2” Olympic barbell sleeves (a 1” size is also sold for standard bars). A reinforced nylon body with anti-slip TPR rubber lining clamps around the sleeve via a cam-based locking lever, operable one-handed. The Magnetic version adds built-in magnets so the clamps snap onto the bar or rack between uses instead of getting left on the floor.

Independent coverage is split. Garage Gym Lab’s hands-on testing describes the design as closely modeled on Lock-Jaw Pro collars but “noticeably lower” in quality, and reports the collar failed outright in a vertical load test – it “immediately yielded to the plates and slid to the ground very quickly.” GymRadar’s 7 tracked user reviews (3.38/5 average) tell a similar story: reviewers consistently say the clamps are fine for light-duty use – machines, curl bars, EZ-bar work – but loosen or shift under real barbell lifts like deadlifts, and one reviewer reports a clamp cracking after about 30 uses. A more favorable editorial review (shreddeddad.com, 4.75/5) praises the hexagonal dual-hinge design and grip, though it reads more promotional (it carries the site’s own discount code) and its score sits well above both the hands-on test and the crowd-sourced GymRadar average.
