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

Good product
Size: 2.5", Style: Closed Hooks
Strong magnets that stay on wall once applied. Definitely holds the weight that it says it holds on the product. Good size to hold my halters in my barn. Would buy again and I think the price was a little high for this product, but it was worth the purchase.
