Using the GearWrench 83115 magnetic parts tray is a breeze. First, decide whether you want to mount it horizontally or vertically on a ferrous metal surface, depending on your workspace and how you're working. If you have non - magnetic items, the swiveling plastic rim can be adjusted to prevent them from falling out when the tray is hung vertically. You can also use the plastic rim as a handle to move the tray around easily. When it comes to maintenance, simply wipe the tray with a clean, dry cloth regularly. The non - scratch magnet means you don't have to worry about it damaging your work area, but still be gentle when handling it to avoid any accidental knocks. Keep it in a dry place to prevent rusting of the steel material. That's all there is to it, and you'll have a great tool for keeping your small parts organized for a long time.
