Ranger's Large Movable Hook is designed with a 6.5" deep flat surface, making carrying large, bulkier materials easier. The hook simply just clips onto the top of a Ranger shelf side panel, so it's easy to install and can be moved to another location without having to drill any holes. It can also be stored away when not in use. The yellow color makes the hook easy to spot, no matter what surface it's on. These hooks are perfect for storing large extension cords to keep them from getting tangled in a shelf or on the floor.
