Ernst has created a magnetic set of socket rails for easy socket access, storage, and transport. Save valuable space and time by organizing your set of sockets. RareEarth magnets used in our socket rails provide incredibly concentrated magnetic force. Keep your sockets upright in toolbox drawers. Strong magnets will pull through thick drawer liner. Magnets are recessed in the plastic rail and will not mar or scratch painted surfaces. This combination of magnetic mount and premium twist lock clips can"t be beat. The Dura-Pro Twist Lock clips still provide all the versatility you have come to expect from Ernst, now with "stay put" security. With a simple twist your sockets are firmly secured in a locked position. Twist in the reverse direction and your sockets are free to remove. The tension is a perfect medium so you do not have to fight with your sockets to lock them into place and you don"t have to worry about them being too loose. Just a simple 1/8 turn and your tools are secured. Add, remove, and insert clips on any portion of the socket rail to fit your custom set of tools. Socket clips click into place, can be easily repositioned and installed between previously placed clips. End stops on each end of the socket organizer keep socket clips securely fastened. No other socket storage item on the market will provide this amount of options. Integrated design will work with other great products from Ernst. Kit includes 1 18-inch Socket Organizer with 15 1/4-inch drive Dura-Pro Twist Lock Clips, 1 13-inch Socket Organizer with 15 3/8-inch drive Dura-Pro Twist Lock Clips, 1 13-inch Socket Organizer with 15 1/2-inch drive Dura-Pro Twist Lock Clips, 2 13-inch Socket Organizers, 1 1/4-inch Drive Face Mount Ratchet & Extension Holder, 1 3/8-inch Drive Face Mount Ratchet & Extension Holder, and 1 1/2-inch Drive Face Mount Ratchet & Extension Holder. 288 socket ID labels included.
