The Lock-Jaw Oly 2 features an improved design to increase strength and holding power over 50% from the classic version.
The larger lever and uni-body design ensures easy installation and removal of the collar during workouts, while the elastomer pads and the resin frame protects the bar and plates from damage.
Lock-Jaw is the best barbell collar choice for the lifters who demand maximum performance and durability from their equipment.
*For use with bumper plates, CrossFit, or Olympic-Style lifting we recommend Lock-Jaw PRO 2 for maximum performance.*
These things do what they say! The plates are not moving!
