Awesome product!!!
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
Wow when they describe these magnets as “super string” they are not joking! Magnets are so strong you must be careful when placing them on your metal cabinet, lest it pinch your finger when the magnet grabs the metal! This is an awesome product. The hooks have a hole in their base that fits over a threaded post / bolt coming out of the center of the magnet and the kit comes with two washers, lock washers, and bolts to attach the hooks to the magnets. Takes about one minute per magnet to assemble. Once on the wall they feel like they will hold a lot of weight though I did not try to test the upper limit. No problem at all holding yard tools and the like. The hooks or arms have a nice rubberized coating and extend about 4.5” out from the wall. At $15 each these seemed a little pricy but wow what a great solution for hanging things on metal walls. They work so well I will be buying more of these! I actually have some other similar very strong round magnets made for a similar purpose … but they do not have the “built-in” hooks like these do and it makes a big difference for the usefulness! Considering all of that I think they are a great value. Item reviewed: MUTUACTOR Updated Super Strong Magnetic Hooks,40lbs, 2-pack

These are great to have
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These are so strong and bigger than I thought they would be in a positive way the price is good for the product. You can take them and put them wherever you need to. They can go on a fridge or transfer to anything magnetic, can go anywhere. These are a need in the home.

Awesome -- they work perfectly
Style: Updated 3.46in Magnet L Red Hooks 2PCS
Got these to store a DeWalt cordless drill and impact driver on the side of a Gladiator garage cabinet -- and they work perfectly for that. The magnet is incredibly strong, easily supporting the bare tools, and seems even to work perfectly well with an 8ah XR battery on the tool -- not that it's necessary since I don't store them like that. I like that the magnet is padded with rubber. Very nice units, I will get more for sure to store other items.

Incredibly strong magnets and thick, robust hooks. Excellent combination!
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These magnetic hooks are really strong. Seriously! Each part is made to carry weight and last. The hooks are built out of thick steel stock. They bolt up to large magnets that grab onto steel surfaces and won't let go. The cabinets in my shop are all steel so these worked perfectly on the sides of the lower units. I have a few #12 AWG extension cords that are bulky and heavy. Truthfully, I didn't think these hooks would handle them. They do without any issue. Another application is a 30' long #10/4 AWG SO cable that powers my powder coating oven. It's usually unplugged and wrapped up. It would often end up on the floor where it was constantly in the way. The outside of the oven is all steel but I didn't want to make holes in it for cable hangers. Again, I didn't think that these magnetic hooks could possibly be strong enough to handle the weight of that cable but they do. And once they're attached, it takes a lot of effort to remove them! Amazing performance!! I'm thrilled with these magnetic hooks. They are super strong and, obviously, simple to use. Importantly, they stay in place as they should. I wholeheartedly recommend these hooks to anyone. Great product! Incredibly strong magnets and thick, robust hooks. Excellent combination!
