The OEMTOOLS™ 22389 Pro Magnetic Socket Tray allows you to take the tray from your tool box directly to the job—sockets won't fall off on the way! Simply remove the back panel from the tray, and you can attach it to any ferrous surface. Outfitted with strong magnets, this tray can handle a full load of tools while vertically mounted. Designed with 5 rows of customizable storage space, you can set the configuration of the 1/4", 3/8" and 1/2" drive studs to fit your needs. Tired of misplacing your tools while you work? If it's metal, it sticks—while designed for sockets, this tray will hold an array of tools.
