Lock-Jaw PRO 2 Barbell Collars/Clamps, 2"/50mm Olympic Bars

Rest assured these collars are staying put on the bar and will not budge! Taking them off and putting them back on is VERY smooth and easy to do. You press the button and unlock the collars. They will NOT come off accidentally, I can assure you of that. They are made of a very tough and solid plastic. The the inside of the collars that grip the bar are of a different solid material that will not slide around. One of the best products on the market. I love the red ones! The price is very reasonable considering how well built they are. At the same time they are not exactly cheap. Worth every penny though 🌟

These collars are amazing the grip the bar and are solid once locked in. They are decent on weight and feel great. They are easy to put on and take off, the color on them is very nice and have survived a few workouts.

These barbell collars are perfect. Effective, easy to use, and seemingly durable. (I've only had them a month.) They open and close relatively easily, but get the job done.

Zero complaints, would buy again!

Very easy to take on and off as well as very strong. I put 90lbs on it and then jumped onto the plate to test and it didn’t budge at all.

This is by far the best quality and functioning clamp. I do Crossfit and dropping the heavy barbells from the full snatch extension is normal. All other clamps I've used, I had to re-adjust every set or two. Not this one! You clamp once and you won't need to touch them until you need to change the weights.

I’ve been using these for a few months. These collars great! They hold to the bar as if their life depends on it. I’ve used them for DL reps up to 405 lbs., and they stay in place, even if dropped. I’ve dropped these with 225 lbs from overhead positions, and they stay in place. The one thing I noticed, is the lock has bent a few millimeters, and it makes locking the collar a bit difficult.

I got this for my boyfriend for his birthday. He loves it and says it works very well. So we would buy again.

I bought the original Lock-Jaw collars when they first hit the market about ten years ago, and they’re still working flawlessly. I wanted to get a second set and was debating between these Pro 2’s and the metal versions sold by Lock-Jaw and Rogue. I’m very glad I went with these, and the build quality is absolutely superb. Unlike the metal version, they are very light so you don’t have to compensate for the added weight. Although I never had any problem with the originals, it’s obvious these Pro 2’s will hold up to much more weight and shock. They are a bit less convenient to release of course, but these definitely feel much more secure on the bar. One thing that should be noted is that with the original lock-jaws once they were locked on, they didn’t move at all. That’s because the circumference of the collar itself became flush with the bar. With the Pro 2’s the collar itself doesn’t actually make contact with the bar, but only the rubber lining. This makes the collar ‘float’ over the bar, so it jiggles a bit if you move it. This actually makes it more secure as the collar is then resistant to any shock when dropping weights or if a loose weight slams into it. In all, I strongly recommend these. They’re definitely worth the money over any Chinese knockoff.

These clamps are awesome! They allow quick release and change of weight plates, saving you time. I highly recommend these clamps, you won’t regret it.

Heavy and solid. You can feel it clamp down hard, but taking it off barbells is easy as.

Very convenient and holding very well after two uses. I haven't yet tried them with more "aggressive" exercises where the bar meets the ground at speed but so far they look very good and strong.

Bought these to replace the basic ones that came with the barbell. The lockjaw ones are clearly quality products and are just really easy to slide on and off the barbell. Great product, worth the little extra.
