Eliminating the time lost to sockets detaching in deep or restricted spaces, this 3-pack locking extension set secures 1/4" (6.4 mm) drive tools to prevent them from remaining stuck on fasteners. The set provides 3 7 and 15" (38.1 cm) lengths to accommodate various clearance requirements during mechanical maintenance. An integrated locking mechanism maintains a positive connection between the extension and the socket until the user manually releases it.
