The Ko-ken Wobble Fix Extension Bars are designed to offer two different secure solutions for holding a socket in place. Wobble-Fix refers to the section of the extension bar that holds the socket, the company says. Specifically, in reference to the flexibility of movement that a socket has when attached to an extension bar with this feature. 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.
