You wouldn't drive a car without buckling your seatbelt, and you definitely wouldn't ride a bicycle without a helmet. You shouldn't use a barbell with weight plates on it without collars (or even pads, depending on the lift). The best barbell collars keep the plates in place so you can lift the barbell in a controlled and consistent manner. But grabbing the first cheap pair shouldn't be the solution for this need because collars help with safety while you're training. The collar should be easy to put on, stay in place while the barbell is in motion, and be easy to remove when it's time to take the weights off the barbell.
So, how do you go about finding the best barbell collars? We researched the 9 best and compiled them in this handy guide so that you can find the right collars for your training needs.

Best Olympic Barbell Collar - Rogue KG Competition Collars
SPECS
- Material: Billet Steel
- Weight: 5.5 lbs. each
- Width: 3"
These are called the KG collars because each collar weighs 2.5 kilograms, which equals 5.5 pounds. These Rogue collars can also serve as extra weight if desired. Instead of a clamp, they are secured by a ball lever handle that is twisted into place. It takes more time to secure these collars, but it is worth it for lifters that train with heavier weights. The hard finish and Rogue branding make these collars look nice as well. Plus, they come with a two-year warranty should they break or need replacing.
What We Like
- Lever handle can ensure that the collar is as tight as possible
- Approved for competitions in both Olympic weightlifting and powerlifting
- Minimal weight tolerance, meaning the weight of the collars are verified

The click you hear when you secure the collar is how you know it's locked on. You will hear that same sound when you open the collar to remove it as well. These collars are designed for high-intensity workouts such as CrossFit.

Best Barbell Collar for Heavy Lifting - Rogue HG 2. 0 Collars
SPECS
- Material: Solid Nylon Resin
- Weight: 0.85 lbs. per pair
- Width: 1.875"
The Rogue HG 2.0 collars have a thicker rubber on the inside to provide even more protection for the barbell, and that's a good thing because these collars are meant for stronger lifters that may drop the bar at the end of a lift or set. The spring in the tab makes it even easier to lock and unlock the collar.
They can be bought in bulk if you have multiple barbells and want collars for each. Of course, one pair will work for all Olympic bars too. Even though they say the collars will last for many workouts, they offer a one-year warranty should you need to replace them.

Best Collar for Specialty Bars - Proloc 1 - Standard Olympic Barbell Collars
SPECS
- Material: Nylon
- Weight: 0.79 lbs.
- Width: 1.8"
Specialty bars are unique barbells that are shaped differently and meant to be used for specific purposes. Examples of specialty bars include safety squat bars, hex (or trap) bars, log press bars, and multi-grip bars. The downside to these bars is that traditional Olympic collars may not fit them.
That's why having a pair of these collars would be a wise investment. They can work on both Olympic bars and many specialty bars. The twisting clamp is what allows them to be tightened down on bars of different sizes. They are also very light. They will be hard to break because they are made of nylon.
What We Like
- Available for standard one-inch bars as well
- Bright colors help them stand out
- Knob at the top makes it easy to tighten or loosen
What We Don't Like
- Different colors cost different prices
- End of the screw that touches the barbell could scratch it

Types of Barbell Collars
There are three main types of barbell collars: spinlock, spring, and lockjaw. They each have a common function, which is to keep the weight stable and in place so the lifter can execute the movements without fear of the weight sliding off. The differences are in how they have secured to the bar.
- Spinlock: The collar has a screw or twist that is tightened down by a lever or handle. They work similarly to screws in general, right to tighten and left to loosen. They can work on both Olympic barbells and specialty bars, but they may need to be reinforced if the same weight is used for multiple sets.
- Spring: The basic spring collar is easy to work with. You squeeze the ends, slide the collar on the bar, and let go. They work the same way when it's time to take them off. They aren't as strong as other types of collars, and they may work their way loose if the bar is dropped repeatedly. Furthermore, if you lose your grip on the collar, it could slip out of your hands. Spring collars are used with both standard and Olympic barbells, but they aren't likely to work for most specialty bars.
- Lockjaw: The lockjaw collars are considered by many to be the strongest. Once on the bar, they won't move because of the way the lockjaw clamps down. Some have covering on the inside to protect your bars while others don't. They are closed and opened with tabs that are on the top of the collar. Lockjaw collars are great for Olympic bars, but they may not work with specialty bars.
What to Look for in a Barbell Collar
First and foremost, make sure the collars you order are sold in pairs. All the choices we have here are sold in pairs, and most collars are in general, but some may be sold individually. You should look for collars that are easy to put on, easy to take off, and if you have an expensive barbell, you should make sure the collar has protection on the inside that touches the sleeve.
If you're a beginner or looking for budget-friendly collars, then spinlock or spring collars may be the best choice. If you train with heavy weights, or you could drop the barbell from a high point like in CrossFit, then lockjaw collars would be the best choice
FAQs About Barbell Collars
How much do barbell collars weigh?
Collars can range in weight between 0.5 pounds and 5 pounds. Lighter collars would be best for beginners or people that aren't focused on strength. Lifters that want to work with heavier poundages should consider heavier collars.
Are barbell collars worth it?
They are certainly worth the investment because of the importance of their function. When you perform exercises such as deadlifts or squats, you don't want the weights to slide on the barbell because it could cause you to lose balance and get injured. The next purchase you make after buying a barbell should be to buy quality collars like those on this list.
Why do people use barbell collars?
People use collars to keep the weight in place so the lifter doesn't have to be concerned about balance. Keeping the weights stable allows the lifter to focus on training the muscles or pushing the weight itself for strength. Collars help keep the lifter safe and healthy while they are training.
