Impact Large Magnet Grip Mount with 3/8'-16 Stud (100 lb)

Wow... This magnet is insanely powerful! If you look at my pictures I provided in this review, there are also instructions how to use this product using common sense in physics and how to deal with it when removing this monster off a flat metal surface. It is claimed to hold 100 pounds, which I don't need to try such thing, BUT, again, before you go crazy with it, how you load the weight, especially heavy loads, it will matter! The same item or load can feel lighter or heavier, depending on the MOUNT you choose and how far it will stick out from the actual base. A little common sense and a small basic knowledge in physics is your best friend on this. I also love the fact that it has a 3/8 thread, obviously. Again, physics... A 1/4-20 for what this magnet supports, it wouldn't do... As an example, I loaded a rather large item such as a Genaray SSL MiniB LED light fixture. Since the SSL's lollipop mount would be one of the most unfriendly loads you can throw at this magnet, as for being a very long mount and extends so far from the magnet's base, it will make the load feel like 20 times the stress. Trust me, it does. So, something that weighs 3 lbs, depending how you hang it, will feel like a 60 pound load. What you will want to do is to keep whatever load you plan to have on this magnet as low gravity as possible, meaning, the shorter the adapter you use, the better and more efficient and SAFE it will be. This way, you'll be able to safely mount some pretty heavy things. Choose a low gravity mount (as close as possible to the magnet's base). You can use a 3/8 baby pin, or a powerful and expensive ball mount. Or, that's what I would recommend for heavy loads. If you're using an action camera, a small LED light, then, nothing to worry. The rubber finish is great! It will NOT scratch any surface, particularly Important when utilizing this item at someone's property, office or Real Estate property. To remove it as easily as possible: please see my pictures included here. The also have text info on them. Conclusion: Strong, doesn't scratch surfaces and it's a large surface magnet. What else could you want...I'm very impressed. [I received this item in exchange for my honest review]
