These Performance collars hold on to the barbell like nothing else and have magnetic sides to attach to the rig or storage racks easily. They have a simple mechanism that provides an unmatched hold on the bar, which easily withstands high rep workouts and dumping of the bar from overhead time and time again. You're also getting an easily adjustable collar that has a simple lever to lock or unlock the mechanism. Too, easy!
If you’re a CrossFitter, S&C athlete, a Gym owner, Coach or like to train at home in the garage without having to tighten up spring collars every few lifts, you should definitely consider a pair of these performance collars.
