The Best Barbell Collars Reviewed

Updated January 11, 2019

Lifting weight can be dangerous. When you’ve got hundreds of pounds of cold steel hovering over your torso, you need to know that those plates are safe and secure. That is why the most important piece of training equipment in your home gym is also one of the smallest and least expensive – barbell collars.

We’ve all used collars that don’t work. Halfway through a set, they loosen and the plates begin to slide. When you’re doing barbell curls that’s an annoyance. But, if it happens during the bench press, it could result in a major injury. In this article, we reveal the 9 best home gym collars to keep you safe when you’re smashing it in the gym.

There are some very good home use barbell collars on the market. Keep in mind, however, that these weight clamps are designed for use by individual home users. In a commercial gym setting, they would end up being overused and would soon lose their hold.

The best barbell collar for his use on the current market is the OSO Barbell collar, which provides you with an aluminum body, solid lockjaw system and is very durable. You will pay quite a lot more than the plastic collars out there, but you won’t regret it.

Our second favorite collar for home use is the RitFit Olympic Barbell collar, with its hardened nylon resin frame and the easy on/of ability that allows you to use it with one arm at a time. Rounding out our top three home use collars is the L-Fine barbell collar, which is made from hardy and durable ABS plastic and features a very efficient and fast on/off the system.
