Ant Mag Magnetic Hooks Heavy Duty Neodymium, 140LBS Swiveling Carabiner

I love these magnets. The magnets have a small, sturdy rotating ring on them that works perfectly as an anchor for nylon ties. Normally that ring has a carbiner looped through it. The magnets also included large keyrings which could be used in combination with the carbiners (or to replace them.) Plus, there are stickers to put on the magnetic side so it doesn't scratch the finish of painted steel. These extras make these magnets one of the most flexible ways to attach a wide variety of things to any ferrous metal, like steel. Another place I'm using them is in the workshop. I can attach tools, fixtures, jigs, extra extension cords, and documentation to each shop tool. I also have steel storage shelves suspended from my ceiling. With these magnets, I can hang things from the underside of those shelves. Most recently, I used them to hold the wiring harness for the lights on a painted steel trailer. There is no way these will vibrate loose while driving down the road. They are stuck to that frame as if they were bolted on. When I got my first batch of these magnets, I tested them by hooking my gigantic fully-filled 64-ounce stainless steel water bottle to the carbiner and sticking the magnet to the underside of a steel table. The magnet held the bottle more securely than I hold it. I was amazed. Most of the other magnets I've purchased seemed wildly over-rated on holding power. These seem a lot more powerful than those other magnets. Are they 140 lb.? I don't know. Perhaps they are, but only in laboratory conditions while attached to pure iron. In the real world, these would more likely support around 50 lbs. when placed on steel. The others I've bought in the past were lucky to support maybe 10% of their rated holding strength on a good day. I only order magnets from Ant Mag now, because the magnets seem to be higher quality and more powerful than what other vendors are selling. Plus, I get them very quickly. In the past few months, I've placed several orders for multiple boxes of these and all of them have been excellent. I seem to discover new uses for these magnets every few days. Highly recommended!

Another brand of magnet I use came with a thin layer of silicone or 'rubber' sheet glued to the magnet surface. This increases the hold/anti-slip performance on vertical surfaces. These did not come with a rubber layer on the magnet surface but it's easily added. Anti-slip silicone sheet with a thickness of 1/64" or thinner and silicone that has some 'tack'. Raw silicone sheet can be purchased from Amazon. I've also used a dashboard anti-slip pad from Handstands. It works noticeably better than silicone sheet I've tried but it tears more easily. For this magnet, cut a 1.5" circle, apply to the magnet surface with or without adhesive and you're done. Once attached, these go from very strong and high performing magnets to very strong and insanely slip resistant magnets. So much so that on a high iron content steel surface, I had concern that I'd damage or break the magnets due to the force I had to apply to remove them. I wasn't able to slide them off the surface to break them free. I was able to pull them off finally but not without some long lasting soreness later in my forefinger knuckle joint. Probably best to use large pliers to grab the carabiner and then slide or pull it off. On horizontal surfaces, there's little benefit from using silicone pads aside from providing some scratch resistance for the magnet surface and the surface it's being applied to. On horizontal surfaces, there's probably a bit less hold with pads but barely worth mentioning with magnets of this strength. I haven't had these long enough to comment on durability and rust resistance but the workmanship and materials are superficially impressive. The magnet housing appears to be stainless steel but the advertising says it's plated. I think the original advertising said it was stainless - not sure. I don't know if the 140lb claim is accurate. Advertised magnet strength is almost always unsubstantiated for inexpensive consumer level magnets and probably exaggerated by some unethical suppliers. I have no reason to believe this supplier is anything but above board but personally, 140lb's seems like a stretch especially in the real world where conditions will vary. I'd estimate that I used at least 50lb's of force when removing the one I described above. Bottom line, I probably wouldn't use these as fishing magnets or otherwise outside in an unprotected environment. Based on other customer reviews, they don't appear to be rust resistant. In an inside environment, they have aged well and are more than suited for hanging things like daypacks, heavy coats and other somewhat heavy objects. Good product, happy customer.

These magnets are No Joke. When they say a strong hold, they were being Honest. I bought this for a yearly calender that I hand on the side of my refrigerator. It has a spiral top, so it is Awkward to find something that makes it hang flat & the heavy magnet can hold it with No Problem. I tried other magnets but as soon as I felt how Heavy these are, I know I picked the Right ones.perfect size, about a the size of a Coin Dollar. 100% Sturdy and Well Made.

Almost returned them because they didn't look strong enough to hold what I needed. But they are powerful little guys. Don't let the size fool you.

These are strong magnets. I always take a few with me when I go on a cruise. The ship is all steel of course, so these are great to have. I could easily hang my tuxedo on a good hanger along with a couple of shirts. You know how it is trying to put stuff on your lapel when it's in the closet. This made it easy to prepare my jacket before I put it on. My wife hung her formals out in spaces against a blank wall. Also stuck one to the door to remember to take our fanny packs and so on. At home, I use these on the steel entry to the garage. I can hang all kinds of stuff. A word of caution: These are STRONG magnets. You'll want to use the included protective strips to prevent damage to what you stick them to. They are really strong. The D-rings are also quite strong solid aluminum since Steel is magnetic. The spring is good so far. They came in a box that I used to keep them in my suitcase, but they did erase my room key. I'd keep them away from your wallet!

Love these, They stay right where you need them

Very strong magnet. Definitely requires some force to remove it from where you place it. Been using it as a coat hanger and has held up and doesnt move from where i have it.

These magnets were super strong and served the purpose I needed them to. My family took our van out to Moab and I was able to hang many things that I needed in my Van life kitchen and bedroom. I was concerned they would jiggle and make loud noises as we traveled across the country, but not a sound! We were very impressed with their durability! We have highly recommended to other Van Life families. The magnets are very strong, sometimes I had to slide them to get them to the edge to get them to come off because they are so strong, which is what I like and why I purchased these. Overall these were an amazing purchase, and can’t wait for other ways I can use these in my home and at work! “Couch to Adventure” Van life vacationers. , from Ohio

Excellent product with a very strong magnet. They were bought to hold the family calendar on the fridge. Does exactly what is required. The calendar is quite lightweight and these magnets could take much more weight than what I am using them for. Once placed on the fridge, they don't move. The option to clip something on to them is the reason for the original purchase. Very happy with this choice, had them for quite a few years and don't see they will ever need replacing.

Funcional

Bought these to help keep our awning in place on our campervan. Used them for the first time when camping in Wales and on the first night we had a severe weather warning for rain and extreme winds. As you can see, Our awning suffered. But these super strong magnets actually held it in place! They didn’t budge! I’m pretty certain we’d have lost the awning if it wasn’t for the magnets. I bought 4 and I’m about to buy some more as I also discovered they are strong enough to stick to the inside of the van which has insulation and carpeted walls. So used them for holding up decorations too. All in all, they are my new essential item for camping. Strong, durable and worth the money. Oh, and despite being strong, you can pull them off easily too without damaging the paintwork etc.

Very strong anchorage. Useful clip as part of the design. Better than anticipated
