Uxcell 1/2-Inch Drive by 3" Impact Extension Bar, High Carbon Steel

Work faster and avoid unnecessary disassembly steps with Impact Extension.
Engineered for use with impact drivers, it reaches past obstructions or into tight, narrow spaces and deliver the torque needed to break loose stubborn fasteners.
A spring-loaded detent ball securely latches onto sockets, preventing them from being dropped or left sticking on fasteners.
The through-hole in the drive end locks onto the tang of impact wrenches or drivers.
To protect against rust and corrosion, the black oxide finish absorbs and holds oil, repelling moisture.
