From our most versatile socket organizer line, the Ernst 2-Tray Combination Socket Boss Pack comes with 6 18” Rails, with room for 44 1/4-inch, 36 3/8-inch and 34 1/2-inch drive Twist Lock socket clips. Keep your sockets upright in toolbox drawers and also hangs vertically for convenient storage. 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. Socket Rails release quickly from the trays with a push of a button. I.D. stickers are included for easy tool identification. Made in the USA. Tools not included.
