MADE IN USA: Proloc collars are a new and innovative way for weight lifters to secure weights to Olympic bars.  The patented (pending) design allows a strong"lock" for attached equipment, and also assures the weights remain secure during any workout.

There are many advantages to using Proloc collars including easy on and off knobs that accommodate all users.  They are also universal and can attach to various size bars (including swiss bar, econo farmers walk, logs, rackable cambered bar, safety squat yoke bars and solid fat bars).  Proloc collars are made of durable nylon plastic to withstand the abuse of everyday wear and tear in the gym.  

Over time Proloc collars will prove themselves to be cost effective as they outlast conventional spring and other collar designs.


"I have been thrilled with these collars the second the staff added them to both Blatt and Strom. I don't do competitive weightlifting or anything like that, but I do love power lifting, and it doesn't take an expert to see that Prolocs work. It doesn't matter if you are doing a 135lb dead lift or a 300+ pound power clean these things won't move! All that readjusting the weights back onto the bar and having to readjust the collar just doesn't happen with these. You put your weight on and tighten the collars and that's it. Throw the weights around if you don't believe me; because these things don't budge!"
