OSO Barbell Collars - Pair - Billet Aircraft Grade Aluminum Barbell Collars for all 2" Olympic Bars

These are fantastic collars! They are easy to put on and off, it is much easier to remove and install them in the OPEN position. Although the NEUTRAL position gives you some room to slide them on and off, unless you pull them off completely straight, they will tend to grip to the barbell.I've been doing sumo deadlifts and they do wiggle loose a tad bit after a few drops (deadlifting 245-lbs at the moment). it's not to the point that the bumpers are wobbling though, after 15 reps total, the collar backed out maybe about 3-5mm which is hardly anything in my opinion.The locking mechanism is great as well! Easiest way I've found to unlocking them (without it snapping back and whipping your finger), is to put your thumb against lock, and your middle or index finger on the metal wedges around the collar and then just push with your thumb. That way, your fingers are out of the way and won't get hit when the lock springs open. Attached a photo for reference on how I unlock my collars.Overall, I am very pleased, the anodizing looks great, much easier to use than my velcro collar straps. These are each about 0.4-lbs, for a total of 0.8-lbs. This actually works out better for me since my barbell is 20-kg (44-lbs), so now it's closer to 45-lbs, now I can stop subtracting 1-lb from all my sets =D.

I have tried several other cheaper collars because I just couldn't justify the expense of the OSO collars. Some don't clamp securely, others were too small and will not easily slide on and off of the bar.These exude quality. They are the correct size to be easily slid on and off the bar, but when clamped down they hold securely. What else do you want from a barbell collar?Do yourself a favor and skip the garbage, pay once for these and don't throw your money away on junk.

Just the way I like them....But seriously, these clamps are of superb quality and craftmanship. They DO NOT move once they're set up. Just so everyone knows, the clamps aren't fully open until you hear it click. It makes it easier to smoothly slide your barbell in and out, just the way you like it.

OSO collars are normally somewhere around 50 bucks so when I saw the price drop to around half of that, I ordered a pair. Wish I'd read the other recent reviews on here before buying because then I'd have known the reason for the huge discount. These are NOT actual OSO even though that's what the fraudulent description says. These were shipped directly from China and NOT made in the USA. I kinda feel cheated. Easy to use and great looking but I wonder how long these will last. If they fail, I will have to send them back.

The collar is tight but seems to work fine. Not sure I would have paid this had I known it was made in China. The last pics shows the part stamped with the OSO name brand. This is not on the part as received and it's not an OSO part which is now owned by Rogue.

I've had these for about a year and a half, used them 4+ times per werk. They still work like new. I use them for Squats, deadlifts, bench press, overhead press, and barbell rows. Loaded up with light or heavy weight the weights stay right and don't budge an inch even when slamming(controlled) the weight down in rows or deadlifts. Best part is they are very very easy to set and release with the lever, my girlfriend who is just beginning strength training has no trouble at all with them. 5/5 would recommend to anyone.

The orange is definitely a good color. Probably one of the best. The grip on the bar is great. The only downside is the snap of the lever when you release it. If your hand or fingers are anywhere near it, you will have a bruise to remember. It hurts! Once you train yourself to stay clear of that minor danger, and once you get over the drag of the rubber at times when pulling it off, you'll realize it's definitely a step in a better design direction compared to the older bulky collars. The trick is to remember to open it up all the way passed the clicking point to fully open it. Then it doesn't have quite the drag. Also, I have yet to see one of these with the reddish rubber inside. Most are made with the black rubber. Not sure what that's all about. Over all I'd say they're way over priced but they're definitely a good quality product with a fairly good design.

These are ridiculous. Weights don't move, at all. I was using the spring looking collars (provided by the gym) but after dropping a barbell loaded with bumper plates more than a few times the weights would begin to migrate outward. This made it tough to do CrossFit type workouts. BUT NOT ANY MORE!! The rubber on the inside grips very well to the barbell and keeps the weights in place. Plus, they look super cool and I feel like I need to lift heavier or people will be like, "Hey that guy has super cool barbell collars but he's kind of a bitch. I just don't get it."One thing of note: these collars snap closed AND snap open. If you are struggling to get them off the barbell it's because they have not been opened all the way. When fully opened they will 'click' into place.
