Easy and works to hold tools
These work very well. They are adjustable so they will hold most tools. If you have a steel door or cabinet and tools, they are must have. I ordered one set and was so impressed, I ordered another

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.
