Perfect
Size: 4.5", Style: Open
These hooks are so functional and great for organization in the garage. Perfect for hanging extension cords and other misc items that you want to have easy access to. Super simple installation; lift the release and move then flip back down to lock again. Very sturdy and magnet is strong. Worth the buy!

Great for shed organizing
Size: 4.5", Style: Open, Size: 4.5", Style: Open
We recently upgraded to a conex/shipping container/metal shed and needed a way to organize all of our yard tools. These work great, the weight holds a lot of items, could be a little longer but we were impressed with them holding everything for over a month now and not moving.

Good product. Know the limits.
Size: 6 Inch, Style: Open
These are very nice. Sure beats drilling holes in your steel. However, 45lb is a stretch. Will easily hold 25lbs. However 35+ is a stretch, especially if your walls shift a little due to be close to a door. Will definitely order more, just important to understand the limits. Thanks.

Finally, a product that meets all of its advertised claims!
It seems to me like this product is always out of stock. Of the ones I have received and been able to use. They work as advertised and hold an incredible amount of weight. It is very easy to put them on and off, but once they are latched down, you could not remove them by hand without bending the hooks I would like to have a few more boxes to use in my steel building.
