MAGNETIC RACK STORAGE
If you're tired of hunting for your collars between every set, these will change your life. The built-in magnets stick to any metal rack or rig — right at arm's reach, right where you need them.

QUICK-RELEASE LEVER
No twisting. No wrestling with tight spring clips. Just flip the lever with one hand and you're done. On fast, off faster. It's exactly how loading a bar should feel.

RUBBERIZED INTERIOR
The rubber lining grips your barbell sleeve so plates don't creep. It also means zero scratches on whatever premium bar is sitting in your pain cave. Your bar will thank you. Your loading speed will too.

FITS ALL STANDARD 2" OLYMPIC BARS
50mm / 2" inner diameter — which means every standard Olympic barbell on the market. No compatibility surprises, no adapters needed. If you run an Olympic bar, these fit.

SLIM PROFILE
Narrow enough to leave real sleeve room for heavy loading. You're not sacrificing plate space for collar space. Load heavy. The collar stays out of the way.

3 COLOUR OPTIONS
Black, Blue, or Orange. Pick a pair to match your setup. Or grab all three and colour-code your equipment—different bars, different lifters, different exercises—bulk discounts available.
Product Details
Spring collars are the unsung villain of the home gym. They fight you on the way in, they fight you on the way out, and somewhere between sets they vanish entirely. They're like the single socks of the home gym world. (Still don't know where either goes. Probably the same place.)
Magnetic Clamp Collars fix all three problems at once:
The lever-based quick-release snaps on and off in seconds — one hand, no tools, no new curse words invented mid-set.
The built-in magnets do the rest: stick them to your rack between sets. Always there. Always ready. Never losing your barbell collars is a genuinely underrated quality of life upgrade — ask anyone who's ever hunted for a spring collar while a loaded bar sits waiting.
The rubberized interior isn't just a nice touch — it's doing two real jobs. First, it grips the sleeve so your plates STAY PUT under load. Second, it keeps your barbell scratch-free, which matters when you've invested in a quality bar.
Slim profile means you're not sacrificing sleeve space. Load heavy — the collar stays out of the way.
Available in Black, Blue, and Orange. Color-code your setup, match your plates, or just pick what looks right. Pro tip: the orange pops nicely against a black rack, if you're the type to lose your glasses when they're on your head.
Fits all standard 2" / 50mm Olympic barbells, including the Arch Nemesis Swiss Bar and lever arm attachments. Every bar worth owning, covered.
Order in pairs, or grab 2, 3, or 10 pairs if you're outfitting a full setup or just done sharing with your training partner.
4.7 stars. 92% recommend. Reviewers consistently mention two things: how much sleeve space the slim profile saves (one lifter switched specifically because low wall clearance made bulkier collars a problem), and how the magnets actually hold on a glossy rack finish — something pricier knurled aluminum alternatives couldn't deliver.
While you're sorting out the small stuff: pair these with workout chalk for a grip that doesn't quit, lifting straps for heavy pulls where your grip would otherwise be the limiting factor, or wrist wraps for pressing days. The full barbell accessories collection has everything else.
Not sure which barbell collar type is right for your training? The collars vs. spring clips breakdown settles it. Sold in pairs. Pick your color and stop losing your collars.
IMPORTANT: The specs listed are for a single Magnetic Clamp Collar. Sold in pairs.

- JMJason M.Verified BuyerRated 5 out of 5 stars1 week agoTight
Great so far. Thin and convenient to have the magnets. Seems almost as secure as my Rogue HG collars. Highly recommend!
Bells of Steel USA1 week agoThanks, Jason! We’re glad the Magnetic Clamp Collars are holding tight and keeping things convenient with those magnets. High praise on the security too. Thanks for the recommendation and for sharing the media!
Yours in strength, The B.o.S. Crew.
- SHStephen H.Rated 4 out of 5 stars1 week agoGood for width and grip
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.
Bells of Steel USA1 week agoThanks, Stephen! We’re glad the Magnetic Clamp Collars delivered the snug grip you needed while saving enough space for that extra plate on each dumbbell handle. Great fit, strong hold, and solid value is exactly what we aim for.
Yours in strength, The B.o.S. Crew.
- KMkris m. M.Verified BuyerRated 4 out of 5 stars1 month agoGood quality clamp, different than my previous version
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.
Bells of Steel USA1 month agoThanks for the review, Kris! Glad to hear the Magnetic Clamp Collars are holding strong and feeling like a quality upgrade. We appreciate the heads up on the magnet placement compared to your previous pair, and thanks for including a photo to show the design change.
Yours in strength, The B.o.S. Crew.
- ASAdeeb S.Verified BuyerRated 4 out of 5 stars2 months agoLove the magnets and the orange colour
These work well my favorite parts are the magnets because it lets me hang them almost anywhere and the bright orange colour.
Bells of Steel USA2 months agoHi Adeeb,
Thanks for the great review! We are glad to hear the magnets are sticking the landing and making storage super convenient. And yes, the bright orange definitely brings a little extra flair to the gym setup 🧡
Nothing wrong with gear that works hard and looks good doing it!
Yours in strength, The B.o.S. Crew.
- BDBrandon D.Verified BuyerRated 5 out of 5 stars3 months agoBOS Mag Collars
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.
Bells of Steel USA3 months agoHey Brandon,
We're happy to hear that you're satisfied with our magnetic collars! Thanks for sharing photos of how strong the magnets really are under load, and for your kind words. Let The Gainz Begin!
Yours in Strength,
The BoS Crew
