Lock-Jaw PRO 2 Barbell Collar - Quick Release Barbell Clamp

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.

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

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

They feel sturdy

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.

quite expensive but overall very good

Excellent and easy to use. They open wider than some collars. The price is worth it IMHO.
