Handy
Size: 4" - Black, Style: Open Hooks
I use an ocean container for storage and have some things that need to be hanging. These are perfect for any place you are unable to drive nails. I bought the stronger ones and have had no problems. Ordered more after trying them.

Work great
Item Package Quantity: 6, Color: Black
Relatively strong hooks. The metal I have them on is thin so the magnets arent as steady as I hoped but thats my fault not the hooks. Ample hook space and solidly built

You need these!
Item Package Quantity: 4, Color: Black
These are not really “industrial strength” but they work great and are decent quality, especially for the price. I bought them to use on a sheet metal barn and they hold halters, rakes and other supplies with ease. Out of curiosity I did toss a dewalt drill in one and it held even though I ordered the medium size and the drill didn’t fit super well.
