Magnetic Clamp Collars - Bells of Steel

Great so far. Thin and convenient to have the magnets. Seems almost as secure as my Rogue HG collars. Highly recommend!

I picked these up for my primary bar collars and was drawn to them for the magnetic function. These suckers grip and hold tight. Then you simply pop them onto the uprights and you won’t lose them. I saw reviews mentioning weak magnets, however for me, they will drag a 25lb plate across the sleeve pretty easily. Couldn’t be happier with their slim design.

I finally decided to refresh my gear after years of using the same collars. I needed something slim to prep for a future short-sleeve barbell upgrade (I have low wall space clearance), and these fit the bill perfectly. Compared to my old reliable HG 2.0s, the profile on these is significantly thinner. They work great for benching and curling—definitely a win, especially since I snagged them on sale.

I was gifted some fancy knurled aluminum collars that cost twice as much (another brand), but the magnets were too weak to stick to my rack and the one-handed operation wasn't so one-handed (just spins the sleeve rather than tightening the collar). I returned those and got these Bells of Steel clamps. I almost went for some knock-offs on Amazon because they offered more colors. I thought they might be the same collars coming from the same factory with different branding. Some of the customer review pictures looked a lot like the knock-offs with beveled edges, but the Bells of Steel "product specs" image has a more squared off look. I chose Bells of Steel for the reputation and I'm glad I did. These are considerably smaller than the knock-offs and I'm sure they grip much tighter... almost too tight. I hope they loosen up a little with use. Unlike those fancy knurled collars, the Bells of Steel magnets stick to my rack's glossy finish. The width is roughly half of a traditional clamp style collar (1" vs 2"). Those traditional clamps look thinner from certain perspectives, but when you factor the twist lever, they're closer to 4" wide and the Bells of Steel collar tops out at 3.75" and it's 3.5" or less from other angles. You probably don't NEED these, but once you have them, you won't use any other collars.

Slim and tough, do the job and the magnets make them easy to put away and find when needed.

I have used over the years so many different types of collars for barbells (spring, twist on with pliers that chip away the paint, cheaper clip versions) and none have been just right. In fact most have been just ok and others were awful. These however are just what I needed.

They come in a choice of colors to either blend in with your gym or stand out making it easier to find them. They are not super huge, and they are easy to open and close securely. There are two things that really make these the best in my opinion 1) They are magnetic making it easy to attach them to a rack so they are never lost when you need them 2) They fit every barbell I have tried. Most others I have tried fit some barbells but vary in how well they hold on or they simply cannot fit wider bars so they have limited use. These even fit my Bells of Steel 7' axle bar. I highly recommend these magnetic clamp collars since they seem to fit every bar and have a secure grip.

These are great. They work as advertised, the magnets are strong enough to stick to the side of a rack when not in use, and the orange colour looks cool.

So far these have been great my old ones were a pain in the neck to find a place to put them while adding and removing weight with these I just stick them on the machine next to the bar and its there when needed

Everyone at my gym LOVES these. They work well and the ability to just leave them magnetically on the rack is amazing. Now we want to get more fun colors.

I bought two pairs and thrown out for various sets I had extremely sturdy no complaints whatsoever.

Yes, they are SUPPOSED to grip the bar tightly. That's the point of using them... and they do! I was kinda nervous about the width but that will allow me to get one extra plate on both sides of my dumbbells handles which was the goal and they fit about perfectly and hold snug as expected.

Good design to cost ratio.

Grabbed these clamps since I loved my original ones so much. They look improved and hold well but they aren't magnetic on both sides like my last pair, only reason I didn't give them 5 stars. Posted a photo to show the changes in design.

These work well my favorite parts are the magnets because it lets me hang them almost anywhere and the bright orange colour.

Got these on sale and they are great for the price! Good magnets.

Love them. I have wanted some magnetic collars for a while now, but have just found the wonderment of Bells Of Steel. I've been very happy with all the items I have bought here. These are no different. They are small, clamp fine, and stay on my rack when not in use. The one con I have found has areal been commented on by another reviewer. The magnets are a bit weak. They will stick the rack, but they also slide down the rack. This does not affect the way they clamp onto the weight plates for a snug fit when lifting though. I've taken to putting them around a bolt on the rack. The magnets hold and the bolt holds the collar. I'd buy it again if I needed another.
