Ko-ken 3763 3/8″ drive wobble fix extensions – SINGLES

Wobble-Fix refers to the section of the extension bar that holds the socket. Specifically, in reference to the flexibility of movement that a socket has when attached to an extension bar with this feature. Wobble-Fix extension bars offer two different secure solutions for holding a socket in place.

The “Fix” solution holds the socket securely and steadily on the extension bar permitting no movement. The “Wobble” solution permits movement of up to a 15 degree angle OR by pushing the socket all the way on, a conventional fixed extension.

My personal opinion is Ko-ken is making the best wobble-extension on the planet. It is said that they invented the concept. The craftsmanship is superb.
