Master Magnetics 07503 Retrieving and Holding Magnet, Durable Plastic, 100 lb, 2.375" Length, 2.375" Width, 1.25" Height with Eyebolt, Nuts and Magnetic Shields, Red/Black

First, I haven't tested the actual amount of weight this will lift, but anything like that will depend a LOT on the shape, thickness, and surface texture of the item you're lifting. But for my use, the specific number of pounds it will lift wasn't relevant.I bought this to use as a mount for a supplemental headlight on my garden tractor. It works perfectly for that purpose! The bare magnets could potentially scratch the hood, so I put down a thin piece of foam underneath. Even with that little space between the magnet and the hood, this has more than enough holding power to keep the light firmly in place through the vibration and bouncing of a tractor in use. In fact, I can't remove it by just pulling up - it lifts the whole hood of my tractor before the magnet releases. I have to grab the top of the headlight and tip the magnet at an angle to easily take it off.My headlight mount required the use of a bolt going down through the housing, and therefore of a nut inside the plastic housing. This was a little tricky, because the magnets on either side tend to pull the nut out of place. But if you get the right size nut (hint - I found that square works better than hex) the sides capture the nut, so once it's started you just have to tighten the bolt and the nut is nicely held in place.One note, to address a different review I saw - if this seems extremely weak, remove the plastic covers! It ships with some sort of sliding guards that apparently keep it from sticking to other packages, or the UPS truck shelf, or whatever. With these guards in place, there is a VERY weak magnetic pull. But once they're removed, it's a very strong magnet.This is just what it says - a heavy-duty magnet in a fairly durable plastic enclosure with useful mounting holes. Useful for a variety of things besides "retrieving".

This is a very strong magnet, but doesn't feel as strong as advertised so I subtracted one star. Comes in handy for me, and the hook can be handy for dangling it when needed as well. If I were to do it over, I would have probably bought one of the smaller rare-earth magnets for the things I use this for.

I use this magnet as a tool in knifemaking to hold the blade during grinding, so my review may or may not be applicable to you. I work with stainless steel and this magnet performs wonderfully. It is every bit as strong as I would want it to be and probably a hair stronger than it needs to be, however that is hardly a negative. Be careful where you set it down- if you lay it magnet side down on a steel surface you may have to work to pull it off. Even on a blade, I have to lift one side to break it free. Pulling it off squarely probably isn't going to happen with your bare hands. For knifemakers out there (for whom this magnet is very popular) I use a layer of blue painter's tape on the magnet surface: 1- because the metal filings come off with the tape, so cleaning the magnet is super easy, and 2- if you have to slide the magnet some to break it free it greatly reduces scratches in the steel.The design is very good for my purposes. The magnets are oriented to one side, so laying it down on its back (magnets up) causes no issue with picking it up. The plastic body is a great heat insulator. It's also great that I can dunk the steel in water without taking off the magnet. The magnet has no steel body to rust like other lifting magnets I have.It says 100lb lift. That's debatable, but it's certainly a powerful magnet. The shields that come with it work very well, so you can chuck this in your toolbox without worrying about getting it out again or magnetizing things you don't want magnetized.

Inexpensive and durable + Strong Magnet here - Not much detail to get into - It's a pretty strong unit considering it's size - I picked up a 55lb+ tool submerged 20 feet in water with this - Handles just fine. The protective covers are great - No worries about wiping out the electronics and it's hook allows for a heavy duty chain or pulley to attach with no problems - NO it won't lift the titanic, but great for small industrial use or wherever you need a good quality magnet.

I was planning on using this magnet to pull a leader down the inside of a wall through 5/8 drywall. It failed a test miserably. I was curious about its actual pull, so I connected it to a digital fish scale. The magnet broke loose at 8 pounds 4 ounces. That's far short of 100 pounds. To add insult to injury, it is not returnable through Amazon.

Simply put, this isn't well made. The plastic case comes with a hole in the top, and one on the side so you can choose where to mount the eye bolt, but the gap you have to weasel the nut into is too narrow to fit a socket into, and too wide to lock the sides of the nut, so you can't really tighten the nut all that well.The magent, well like many other reviewers have posted 100lb rating is pure bunk. 25lb pull at best. Their rating is false advertising at best.It will do one of the tasks I bought it for just fine. Picking up screws and nails off of my wood shop floor. But beyond that, it is a waste of money. Albeit not all that much money.

I was a little mislead by the strength of this magnet. It says '100 lb' but I didn't see that. It is a strong magnet, and the ability to mount the anchor on the side or in the middle is good, but I think unless what you are attaching to is very flat, 100% iron or just ideally shaped to match this magnet, you'd be lucky to get 25lbs. I attached it to a steel shelf, and yes, I had to give a pretty good pull to get it lose, but I don't think it was 25lbs or pull, and I know it wasn't the same as lifting a 100lb weight (the amount of equivalent 'pull' I would have expected).So, nice little magnet, sure. Good if you drop something metal down behind something that isn't attracted to magnets, so you could lower this down and pick up whatever fell, but for something like dredging or otherwise trying to pick up things 'blind'? I don't think so. It's okay, but not quite what I think was advertised.
