Magnetic hooks
Color: Black3pro
They are nice magnets but don’t hold much weight and slide down the metal wall. They are good for small lighter items. Really don’t see them as heavy duty.

Great for organizing
Color: Black3pro
Arrived as scheduled. Just as pictured. I'm happy with my order. They Do Require full contact to support weight. Panels with bends cut down on what they hold ( slide down under load) I put a piece of tape below the magnet & it stopped the slide. They work great for my smaller shovels & tools.

Perfect. Strong Magnets. Good Plastic Sleeving. I have bought Twice.
Color: Black3pro
Very Handy! I ran out of room for my cordless tools and had an entire side of my toolbox. I bought these and hung the tools on them. Problem solved. No fasteners, no extra wall space. They hold even my heavier cordless tools.
