Included with most starter kits, the accessory magnet package provides two additional backer magnets and two adhesive-backed tube runners. The magnets provide additional magnetism for the misting clips or you can use them to add new locations. The tube runners have a 3m backing to help run your system pretty much wherever. You want to clean the surface before adhering the magnet to any surface.
Additional magnets are always helpful. If you are having an issue getting one to hold, simply add another for more magnetic force.
