POWER GUIDANCE Magnetic Barbell Collars

These replaced another pair that had a too small unlock tab. These grip like crazy and are **EASY** to unlatch. And I didn’t even realize they are magnet (there are non-mag ones too), which is great - just slap it on the side of the rack during plate changes.

They have a good thin profile on the bar, after using a while they get easier to open/close. For the rack, it really is cool to have the magnets so they can be kept accessible and out of the way. I have a curling bar so I don’t switch the weight on it much, these collars keep the plates snug so they don’t rattle. For the rack where I need to unplate it often. The magnets make very easy to keep the collars in reach. Plain wire collars are fine, but these are definitely advantageous.

one of the collars doesn't fit out of the box.....i use standard olympic 2". hope i can loosen it enough to be useable... the magnet is a good concept, but in practice it can become a bit obnoxious, getting stuck to other collars and weights. careful with it around your electronics!

I bought these on a whim because they looked interesting. The magnets in them i though were gimecky, but turns out theyre surprisingly useful. They hug up to the weight plate quicker because of them, and I could imagine they hold onto 5 or 10lb additional plates outside of the clamp if you're tossing them on for a quick set. These are great, and I recommend them if youre looking for a set of clamps

Wouldn't trust them to hold a lot of weight, bit they work or having a few plates on the bar. The plastic flexes a bit when clamping so the quality doesn't seem great but working so far. The magnets aren't great either. They kinda stick to the rack but will slide down.

We use these ina commercial gym setting and they are durable and so far, indestructable. If they servive meathead gym bros, they will last for you.

I've been lifting weights for nearly 50 years now and have a complete home gym that includes dozens of Olympic plates, bars, benches, kettle bells, etc. I rarely write reviews, and this is the first time I've submitted a review for a product I didn't award 5 stars. I grew up using the traditional "spring clip" collars, but when the wider, "mechanical mechanism" collars came on the market they were such an improvement I bought 7 pairs and retired the spring collars. The ONLY drawback to the new collars is the amount of space they take up on the plate racks when they're not in use. As far as I'm concerned, a good pair of collars have two attributes. First, they need to fit snugly around the bar to ensure safety, especially when you're lifting significant amounts of weight and jerking the bar, as when you're "cleaning" them prior to an Olympic press or doing squats. Second, the user or spotters should be able to remove and replace them quickly when you're changing the amount of plates on the bar frequently, especially when you're dropping the amount of weight on the in small increments between sets, as you do when you're doing "burnouts." Similarly, if you're lifting with a partner, the vast majority of the time you're at different strength levels and will have to add or remove plates as you alternate between sets. In both cases removing and replacing the collars as quickly as possible, so you should be able to do so instinctively and without pausing to look at or fiddle with the collars. I can't speak for anyone other than myself, but when I'm exhausted it's hard enough to keep track of the amount of weight you or your partner used during your/their previous set. With that said, I bought these collars and paid roughly twice the price of a quality pair of "mechanical mechanism" collars for two reasons. First, I assumed the "magnetic" feature that differentiates these collars from all it's competitors would allow me to save space on my plate racks by simply sticking them to the center bars of the racks or, better yet, the support structures of my squat rack or lat racks. Second, I also assumed from the photos of these collars I'd be able to release and close them instantaneously with their distinctive "single lever" design. I was wrong on both accounts. While these collars do an excellent job keeping plates on a bar firmly and securely, it takes an inordinate amount of pressure to both secure them and release them, far more than it's "mechanical mechanism" competitors which appear to hold plates in place as securely as these do. More importantly, what prompted me to write such a detailed review is the fact the magnets in these collars are almost laughable, as the short video I've included demonstrates. First, only one side of the collars are magnetized, so even if the magnets were of sufficient strength to support their weight when affixed to a metal surface, they'd fall off 50% of the time unless you used a marker to identify the side with the magnets. As it is, the magnets in these collars are so weak they fell off my refrigerator door when I tried to affix them next to a heavy, thick notepad on my refrigerator I use to keep track of items I need at the grocery store...and the magnet that keeps that pad securely in place is merely 1 mm thick and half the size of the nails on my "pinkies." I tried to add a second video demonstrating the type of magnets that would have obviated the need for this less than stellar review. If you're a dumbell enthusiast like I am, you're probably familiar with a wonderful product called "plate mates." Platemates are small, metal, Rubber-coated "donuts" weighing either 1.25 or 2.5 pounds that have extremely strong magnets on one side. They attach securely to the ends of traditional "hex" dumbells that allow you to increase or decrease the weight of dumbells by 2.5 pound increments. As you probably know, 5-50 pound "hex" dumbells are sold in 5 pound increments, and after you've hit 50 pounds they're usually only available in 10 pound increments. As I've gotten older I've transitioned from free weight to dumbell workouts, increasing my repetitions while decreasing the amount of weight in order to maintain muscle mass but avoiding the increased danger of muscle tears and pulls. Both the 1.25 and 2.5 pound Platemates are behemoths compared to these coats, yet their tiny magnets are so strong they literally jump out of your hands and onto the ends of hex dumbells when you're placing them in position and stay right where they are regardless of what type of dumbell routine you're doing. I only mention Platemates because the manufacturer of these collars could easily have incorporated the same strength magnets into them but opted not to do so. The adds for collars featuring the same slim, unilever design as these collars tout them as being "slim enough to fit in your gym bag," but I've never once brought my own collars to a gym. Of course if you belong to a gym that doesn't supply collars for their Olympic-gauge bars, that might be a valid consideration in favor of buying collars with this design. I should stress I haven't purchased or used any other brand of collars with this design other than these, so perhaps they're easier to take off and replace than these are...or you could just replace your big bottle of shampoo or conditioner with a travel-sized one and keep using your "mechanized mechanical" collars.

Have a Rogue bar, nothing out of norm, being using a pair of cheap plastic collars, get this pair for an upgrade. The diameter is small, sliding them on and off the bar is not easy. It requires quite a bit force to clamp it down. The thin yellow/blue/red part made it particularly difficult to clamp

Easy to get on and off and they clip in place and don’t move until you unclip them. What more do you need? A huge improvement on my clip game.

Some many collar upgrades in recent years, but these are now the best I feel. The are stiff for opening the first time or two, something noticed on all 4 purchased, but they aren't bad after, but you sort of have to have a strategy for opening and closing. Good news is that they are very tight, and hold very well. The magnet part keeps them up against the plate for when you lock, allowing ease with cleaning up slop in that. This is still present somewhat with bumpers and the typical center metal ring being enough. I loved the colours as well. Best of all is that they are half the width, which for aspects like our trap bar for deadlifts getting near maxed out, this allows for another 10/15 lbs plate with the space saving, which if you have gotten to the end of the sleeve, is big. all in all very happy. EDIT two months later I've attached photos of a break in the arm. These are used solely on a deadlift bar, so not as much use as some other collars I have. It breaks, as you can see in the last photo, because there is a manufacturing seem at the end of the arm where thr pin goes through. There is upward movement when opening the collar, and this clearly puts stress on this, and leads to this. I'm hoping the manufacturer responds with an answer or that this is a fluke and replaces them, and if so, I'll change my rating, but for now, after so little time and use, they are highly not recommended!

Exactly as advertised. They work great and I am able to remove with one hand if I'm holding more weight in the other hand

This will not close a standard barbell. Hurt my hands trying to get these too close. Unfortunately I missed the return window or these would be going back.

UPDATE: After I wrote this review, seller contacted me to offer either a replacement or full refund. That doesn't make this particular product any more suited for my needs, but the excellent service means I'd buy from this seller again! Design is very nice and all and the idea of them being magnetic was supposed to make them safer when handling heavy loads... theoretically! I had them for 3-4 months, but since I only used them for my heaviest deadlifts, I used them on only 4 workouts and only on the last 2-3 sets or so. It seems that they couldn't handle the lateral pressure from the plates as soon as the bar bent enough! Since I use a fairly stiff bar (BoS PL bar) it starts bending at around 405 lbs. That's when I used the clamps anyway. So they withstood 3 workouts ending at 455 or below, but on my last one, on the last "warmup" set @455 lbs, one of them broke and set the outermost plate loose which hurt my back and prevented me from finishing my workout! That's dangerous!!
