Lock-Jaw PRO 2 Barbell Collars Olympic Barbell Clamps 2 Pcs – Heavy Duty Bar Clamps for 2” & 50mm Olympic Bars – Secure Weight Bar Clamps for Strength Training & Home Gym Accessories – Quick Release

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.

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.

Got for gym, real solid stuff

The first time I used these Lock Jaw Pro 2 collars was at a powerlifting gym and as soon as I picked them up I knew these collars were serious. I use these on my Texas Deadlift bar and they are as solid as my old school 5 lb comp clamps. If you are thinking about getting a set of quick release collars PLEASE PLEASE PLEASE DO NOT buy the cheapo collars. Once these collars make contact with the bar you can FEEL the "squeeze" on the bar and then it snaps tight. .These Lock Jaw collars will also clamp tight to ANY BAR even the cheapo bars that have a slightly smaller sleeve diameter. What I like best about the Pro 2 collar is it has a "Snap Latch" which is like an added level of safety. The main latch will not release unless you press the "Snap Latch" first so repeated slamming will not pop open the main latch. To be completely honest I liked the 2" Pro 2 collars so much I also bought a set of the Lock Jaw 1" collars. They are just as good as their big brothers and being as inexpensive as they are, about $18.00 a set, I'm going to invest in a few more for my various other 1" 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 🌟

There are cheaper versions, which I have not tried, but I wanted to get the Lock-Jaw brand due to their reputation. Super happy with these. One tip for easy use: When engaging or dis-engaging the locking tab grab and turn the barbell sleeve while holding the clamp and lock tab. Super quick and easy.

Awesome find. Really locks the plates in place

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 strong and safe! You feel the difference! Really good!

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.

Absolutely love these - great quality and fit on both different size bars that I use at the gym perfectly.
