Magnetic Barbell Collars [Bells of Steel] Premium Weight Bar Clamps, Quick Release Barbell Clips, Olympic Barbell Clamps, High Strength Nylon Gym Clips, Pair, Black

I bought these collars for the ends of my barbells in my home gym, and they’ve been exactly what I needed. My bars have a shorter sleeve, so there’s not much room for bulky collars, but these are low-profile and fit perfectly. They hold the weights tight with no slipping during lifts, even with some heavier plates. Easy to snap on and off, and they feel secure once locked in place. For the price, the quality is solid, and they’ve made workouts smoother. I’m already thinking of grabbing another set in the next couple of weeks just to have spares or use on my other bar. Great little upgrade for a home gym setup.

Perfect size for a curl bar and magnetic is awesome. Very happy.

Bought 2 pair for dumbells to replace the cheap spring collars. These are great and take up less space on the bar. Room for more plates!

Love these collars! The slim design is nice especially if in your gym bag or using to secure weights on a rack. They do have great hold and I would compare them to similar Lockjaw products in that manner. I originally bought these to secure plates to the rack in my home gym since I have a little one around and want to keep them safe. I then tried them out at my local box gym in the winter and loved the grip and portability.

As other reviews have noted the magnetic force is not strong enough to hold these BOS barbell collars onto a smooth surface. However, if you have a textured surface they will stay where you put them. I like that BOS added the magnets, and they hold on the surface I leave them on. Just know that you might not be so lucky if the surface you want to use is smooth.These Barbell collars are very convenient to use with their very well designed leaver arms. I have used many styles over the years, and these are honestly my favorite to use day to day. The locking, unlocking, and mounting to a barbell are very easy. The way the lever arms work, the collars stay fully open so putting the collar on is a one handed operation.That said, the clamping force is not great on 50mm bars, these move down the barbell noticeably during every set I use them, so I do not use them for high weight explosive exercises. However, for 2/3rds of what I do, I love to use these. They do hold a little better on standard 2 inch bars though, but again they do move around a bit more than some of my other clamps.

Works great. I bought another pair for my other bar

Strong hold. My 92yr. young father-in-law who I work out with loves then on his curl bar weights feel tight and more room for weight.

I really like that they are magnetic, they easily hold by the power rack posts without any risks of losing hold or getting lost. They grip the bar well. What I don't like is that she one day of use, one of the collars severely opens more at their middle connection when it is in lock position. This to no doubt result in a failure one day. I would've given then 5 stars if I hadn't experienced this issue. As someone that owns a BoS Manticore Power Rack and their Rackable Curl Bar, I can honestly say, the magnetic collars need some attention.
