Proloc Black Barbell Collars

best collars ever. They never fall off and hold on any amount of weight I throw at it. The only con I have (they are too good to knock a star off) is that the tightening screw knobs are fragile. They are made of a hard plastic unlike the main collar. if you drop them expect them to break. This happened the first day for me on one. They still work just as good but it did happen.

Hands down the best collars. These things work perfectly. They’re also really durable and light. Was a little turned off by the price but I’m glade I paid because these are worth it.

No thrills but they get the job done, and are the best option on the cheap for specialty bars. The twisting knob works pretty well, not quite as fast as lock-jaws but nothing to complain about here.

These collars are great. The tightening mechanism is very innovative, and they have an extremely sturdy build feel to them. Looking forward to using these on my bar. Definitely worth the $40!

Best collars ever made. Spendy though :-( These don't move....period.

Works well for squats and bench, keeps the weights dead solid on the bar. But whenever you use for deadlifts or other movements, where the weight interacts with the ground, it starts making its way further from the weights, wish it stayed better.

Love them. Slick. They do not scratch up barbell sleeves like metal spring collars do. The combined weight of two is about 14 oz, so I just consider it one pound total.

Excellcent collars. Great hold and light weight for easy storage in my gym bag. They dont slip at all even on max deadlifts
