Lock-Jaw Barbell Collars were designed to be user friendly for both men and women while safely and securely retaining weight plates onto weight bars during use. Lock-Jaw Weightlifting Collars feature a proprietary Patented design that are constructed to integrate with regular barbell bars, dumbbell handles and Olympic bars. Constructed from a solid nylon resin frame and injection molded pressure pads, Lock-Jaw barbell and dumbbell collars are almost unbreakable and will provide you with years of safe dumbbell and barbell workouts. They are compatible with plates with any coating such as painted/baked on enamel, rubber and urethane. What makes Lock-Jaw the best barbell collars? Their one-handed installation and removal via the single-action cam makes weight changes quick and easy which can be especially useful when performing drop set exercises.
