* Wobble Extension Bar is designed to link with a fulcrum, to provide a stronger force.* Made of resilient chrome vanadium steel for great strength.* The fully polished chrome finish makes for easy cleaning that is resistant to corrosion while the knurled handle makes it convenient and easy for finger turning.* Spring-loaded balls securely latch onto sockets, preventing them from being dropped or left sticking on fasteners.* Two tools in one: fully inserted for extension or partially inserted for wobble extension.* Providing offset clearance for hard-to-reach fasteners.
