MLTOOLS Twist Lock 18-inch Socket Rail Socket organizer 

MLTOOLS 18-inch Universal Socket Organizer. Twin serrated edges provide 2-sided socket and accessory loading. Additional socket clips and other add-ons snap on both sides for maximum socket storage. It can hang vertically for convenient storage. Dura-Pro Twist Lock clips provide all the versatility you have come to expect from MLTOOLS, 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.
