Lock-Jaw Pro Collars
Gymleco’s Lock Jaw PRO barbell lockers are specially designed for barbell training and are therefore of the highest commercial quality.
With exceptional grip and pressure pads, Gymleco’s Lock Jaw PRO locks prevent the weights from moving during heavy strength training and protect the weight plates for a longer period of time.
The quick release mechanic means that you can quickly change weights and also with one hand if that were the case.
The barbell locks are designed and developed for commercial use and are therefore well suited for the gym, functional fitness box and other professional training rooms.
