10 Best Barbell Collars (Review) in 2019

Greententljs created one of the best barbell collars we’ve ever tested. You see products priced this low and think, “There has to be some catch, something wrong with it.” Nothing could be further from the truth. Not only do Greententljs Olympic Barbell Lockjaw Collars create an ironclad grip, but they’re doubly reinforced by the steel skeleton and high-density rubber grips along the interior. While they keep the exterior crafted out of ABS plastic for customization, they will get scratched up after a few trips to the gym (which doesn’t impede upon their function). You’ll want to ensure the screws are tightened properly each time you go to use these, but with a bit of attention, you’ll have these inexpensive barbell collars for well over a decade.

While plastic isn’t our first choice for quality barbell collars, we were blown away after testing Clout’s Quick Locking caps. First and foremost, these are super simple to use, partially thanks to the textured thumb grips on the release latches. These pop off and on like it’s nothing, and you have to fall in love with the ease of use. Clout did fall a bit short on the lack of an internal steel frame like most plastic-encased models have; these are straight ABS plastic, and as such, are prone to breaking far more easily. That being said, you’ll still be able to pop them on a 2” Olympic barbell with no problem. The only metal found in these are in the aluminum hinges, which help keep that tension when these caps are closed. They are perfect to always have in your gym bag.

You’ll hear us rant about nylon in the buying guide below, but Iron lab did something completely different. This is a highly durable compressed, hardened nylon. That being said, they didn’t include a steel skeleton, so it still remains as breakable as plastic. One of our favorite features is the bright red release tab, allowing you to pop this off of your barbell without any hassle whatsoever. This is especially useful if you’re bringing your own to the gym. Iron Lab did a fantastic job at designing the rubber grip pad. We were hesitant based on its narrowness but were pleasantly surprised to find that nothing is going to budge on Iron Lab Olympic Barbell Collars. As an added bonus they also include a lifetime warranty. Once a customer, always a member of the Iron Lab family.

OSO is an all-American brand, one that can be found in gyms all over. Their Premium Barbell Collars are built just the way we like: full aircraft-grade aluminum construction. OSO only falls short in a few areas. For one, the color you see isn’t the color you get. Second, when you release this spring, it’s going to bounce with a ton of force. If you’re careful, you’ll have no problem. That highly tense pull-back is a testament to how powerful these barbell collars really are. Even with their rock-solid design, OSO still includes a two-year warranty on the locking mechanism. Those of you who are really motivated to hit the gym hard will be happy to know that these are rust-resistant, so a spilled water bottle or layer of sweat on the collar won’t damage or discolor them at all.

We all know CAP, the creators of budget-friendly home gym equipment. Barbell Spring Clip Collar is one of their diamonds in the rough: a simple, no-frills collar that gets the job done. We’re not here for style points; it’s all about function, and CAP delivers. These are crafted out of full stainless steel, providing a longer use on the coil, destined to last for a decade if you let them. The only thing that isn’t going to last that long is the luster on those levers. While the grips are nice, they will show wear and tear from sweat and finger oil after a few uses. The aesthetics don’t exactly hold up when it comes to the chrome plating, either. While they’ll look weather before long, we consider them battle scars. CAP won’t leave you hanging.

Lock-Jaw made a lockjaw barbell collar. Fitting, right? They took their time to ensure this was the best it could be but unfortunately fell short on a few key features. We’re big fans of the maximum surface traction thanks to the interior rubber padding. This helps prevent scuffs or scrapes to the barbell, which can be a Godsend if you’re using public equipment. However, this is a short-term investment. You’ll have these for an average of two years before the hinge rods are a bit too loose to be of use to you. On that note, they’ll need to be tightened fairly frequently to upkeep performance. You’ll get your use out of them for the price you pay, but keep in mind that Lock-Jaw Hex Collars exclusively work on 2” Olympic barbells, nothing less.

Following the fairly standard hexagonal design, RitFit took to a familiar take on the classic barbell collar. They really hit the nail on the head with most problems that barbell collar manufacturers make, by increasing their overall rubber grip contact area. They fell a bit short on the locking latch design; it rests right up against the cuff and is a pain to pull off as a result. Apart from that, we’re not fans of hardened nylon resin as a base material. That being said, RitFit is still rated to last for well over five years with proper care. Just keep in mind that scuffs and sweat markings are going to show up on this in no time. Don’t forget to check out our guide to the best weightlifting shoes for more great fitness equipment.

It doesn’t get any more simplistic than this. Dark Iron Fitness created these ultra simple Barbell Collar Clamps: you slip them on, turn the lever ninety degrees, and you’re locked and loaded. Apart from them making it easy to use, it’s also enormously inexpensive. That comes at a cost, however: you’ll expect to get about two years of use out of this, and the manufacturing process is rough. There will likely be sharp juts of plastic that may need to be smoothed out, but it serves its purpose well. The good thing about that is you can enact your lifetime warranty. So long as you register your collars within a week of purchase, you’ll be able to get free replacements for life should they break down on you. Be sure to combine these with some of the best adjustable dumbbells from our list.

We’re in the bottom tier options here, and Power Guidance has their fair share of issues. While you’re only going to get a tight grip on Power Guidance Weightlifting Barbell Clamps for a couple years at best, you will get a wide rubber contact surface, and one of the most simplistic operations of any barbell collar we’ve used. It’s a lockjaw style collar with a textured locking tab and a durable release lever. Popping these on and taking them off is a walk in the park. Oils and sweat from your hands will show after your first use, tarnishing the aesthetics of these collars early on. But you aren’t really here for style, are you? Durable enough to accompany you to the gym for two years, and fitted with a short-term money-back guarantee straight from the manufacturer which makes them a perfect fitness gift for any man who loves to workout.

Last but not least, we have this little gem. Few inexpensive barbell collars will have tension and pressure like these. You get a full aluminum construction, ensuring a long lifespan on these collars, while also resisting rust and standard wear and tear damage. The latch on iHeartSynergee Locking Olympic Barbell Collars is very powerful, which is both good and bad. Great tension, a rapid release that’s a bit startling. Our only major complaint with iHeartSynergee’s product is that they added unnecessary bits of aluminum all over, jacking up the cost a bit. At the end of the day, these will accompany you to and from the gym without issue. If you were to run into an issue, the manufacturer offers a money-back, product replacement guarantee.
