Wera 8796 LB ZYKLOP FLEX.-LOCK EXTENSION. LONG. 3/8" FLEXIBLE-LOCKING EXTENSION, LONG 3/8" 05003592001

When you absolutely need your socket to stay attached to an extension this is just what you need. The lock/unlock button is just stiff enough to make sure your socket doesn't accidentally come unlocked and add extra time into the job at hand due to an unwanted "socket hunt" from a socket slipping off the end of the extension and falling inside an assembly you're working on. Add in the functionality of the knurled base of the extension and the spinner sleeves down the shank of the extension and all in all this addition to your tool box will be well received.
