Works Great!
Color: 2Pcs-Large L Hooks-Orange, Color: 2Pcs-Large L Hooks-Orange
The hooks were the perfect length and strength to hold the decorative fence edging I was wanting. The magnets were also the right strength. I would buy these again!

Heavy duty - they have their limits
Color: 2Pcs-Large L Hooks-Black
These don’t hold a regular shovel, the magnet isn’t strong enough. They do work nice for plastic snow shovels. I use them in a Wick steel building. Nice to not have to drill into the walls. The depth is nice on them.
