OSO Barbell Collars

OSO Barbell Collars are manufactured in Columbus, Ohio from the same type of 6061 Billet Aircraft Grade Aluminum alloy used in aircraft construction. The OSO Barbell Collars deliver on functionality, too--creating a secure hold on the bar through repeated, high-impact drops, and allowing easy adjustments or removal with a simple lever and lock/unlock mechanism.

All that being said, the first thing a lot of lifters talk about with the OSO Barbell Collars is how they look. Shaped like an industrial gear, the collars' old school design is paired with some bright color options: blue, green, orange, pink, purple, red, gold and gun metal.

For Oly lifters, CrossFitters, or any athlete looking for an upgrade from basic spring collars, OSO Barbell Collars are a nice option.

Rated 5 out of 5 by from Unexpected Perfect Fit!! I had bought the hot pink collars to go with my hip thruster lite bar. This bar is overly thick and it fit perfectly! I use them all the time. Not only are they stylish, but stay when clamped and I have no fears of it slipping. Its easy to take on a off and my hands are hurting anymore from the clip type closures. Great purchase!!!

Rated 5 out of 5 by from Barbell Collars GOOD quality , eazy to use and works great. I've had no problems with them and I'm happy I went with these instead of the more expensive ones. Saved some $$$.

Rated 4 out of 5 by from Great product It was a little hard to get the collar on the bar the first time, but over time it's getting broken-in and easier. It's a great product.

Rated 5 out of 5 by from Perfect Excellent product. Keeps the plates on securely and tightly as well as being easy to put on & take off.

Rated 5 out of 5 by from Great grip Got the OSO collars a month ago and they've been nothing but great. Realy tight fit on the bar. Only complaint is that they tend to scrape the sides of the bumper plates, very minor but worth at least noting.

Rated 5 out of 5 by from Solid Solid construction, lightweight, smooth action. They go on and off easy and don’t budge. Buy these. I went with green and the color pops!

Rated 5 out of 5 by from Easy to use, love the colors! Used to using cheap spring collars and upgrading to these was like upgrading from a rotary phone to a smart phone. These collars grip insanely tight, but are so easy to release and take off the bar. The green color is beautiful and I love the pop of color among my sea of mostly black bumper plates. They seem pretty durable too, I've dropped them a few times and the color didn't chip or scratch at all. I even dragged one along the concrete while pulling plates off after deadlifting, no scratches or anything. They're a lot more expensive than spring collars, but I highly recommend them.
